WHAT IS A COB LED?

Pictured: DRAPER 5W COB LED RECHARGEABLE WORK LIGHT WITH WIRELESS SPEAKER (YELLOW) 90004

COB stands for "Chip On Board".

It is possible to say that COB LEDs became available in the lighting market in about 2007. Initially the market was sceptical about the benefits of COB LEDs because the way they are constructed allowed LED manufacturers to put extremely high powered light sources in small package.

Like a lot of new technologies, there were teething problems, mainly associated with heat management and thermal resistance. though now several lifetime tests have shown that COB packages are very reliable, if heat management is done properly.

These issues have now been thoroughly resolved as demonstrated by the modern reality that every contemporary major LED manufacturer and package maker has COB LEDs as part of their product range.

What are the advantages?

COB packages present excellent uniformity of light from light emitting surface. This is important especially if you want to avoid multiple shadow effect, which often occurs with SMD based lighting solutions. COBs also display superior light distribution. The fact that they are a single light source results in longer battery life, so they are far more economical & better for the environment. From a technical perspective, COB LEDs are also much easier to test. You only need a COB LED constant current driver and a heat sink such as a piece of aluminium.

It is clear that COB LEDs have been very important development in the LED lighting business. This great innovation has allowed an increase in the potential power which can be used inside one LED package by an exponential amount.

What size space heater do I need to buy?

KEEPING WARM

Space heaters allow you to add targeted warmth directly where you need it. Simply find your ideal heat level on the thermostats and enjoy immediate warmth. Portable heaters are also ideal for rooms with inadequate heating or spaces where central heat can’t be installed. Here at Scion Supply we offer a broad range of heating solutions to suit every space.

Personal Space: Consider a personal heater like the Airmaster UFH2TN for under a desk or in an office cubicle. They heat small spaces quickly but shouldn't be used in large rooms. Make it even more personal with the Dimplex DDF250 Desktop Heater which even incorporates a USB port for charging your mobile phone or tablet.

Bedrooms/Offices: If you're looking to cool a standard bedroom or office, these heaters will do the trick. Have a look at the compact Airmaster CRMINI oil filled radiator which provides an instant flow of heat and is completely silent meaning it won't disturb your sleep during the night. If you're looking for something with a little more punch, the CR2T provides a maximum of 2000w of heat easily controlled via an adjustable room thermostat and a 24-hour timer with 15-minute segments.

Large Rooms/Basements: These heaters are designed to heat entire rooms and large spaces. Find the one that's best for your area; have a look at the the newly released Draper ESH2000E a 2kw space heater or the Faithfull Power Plus Ceramic Fan Heater

 

Ceramic heaters like the Faithfull Power Plus Ceramic Fan Heater use positive temperature coefficient (PTC) technology which gives a fast heat up time and, once the pre-set temperature is reached, the power goes on stand-by. It only cuts in again once the temperature drops below what was pre-set, thus saving electricity. Their emissivity rate (the degree at which material can emit electromagnetic waves) is high so the heat tends to last a long time in relation to the time required to reach the desired temperature. 

Garages, Workshops, Warehouses: When it comes to the largest areas, you need to look at our industrial space heaters like the Jetforce DSH1750 - a 175,000 BTU (51kw) diesel/kerosene space heater or, if you prefer Propane, the Jetforce PSH125SS Propane Mix Space Heater which provides 125,000 BTU (37kw) of heat.

Space Heater Sizing
It is important to purchase a room heater that’s rated for the approximate square footage or dimensions of your space. 

Why Heater Size is Important
An electric space heater that’s too large will consume more energy and lead to higher utility bills. The opposite is also true: buying a space heater that’s too small will simply fail to adequately heat your space.

Space Heater Square Footage Equation
You can determine the right size by using heater wattage output. As a rule of thumb, you'll need roughly 10 watts of heating power for every square foot of floor area in the room.

This means that a 1,500-watt heater can be the primary heat source for an area measuring up to 150 square feet. If it’s used as a supplemental heating source, however, it covers a much larger area.

Use this chart to determine the right power output required to heat your space:

WELDING FUME – CHANGES TO HSE CONTROL EXPECTATIONS

The Workplace Heath Expert Committee has endorsed the reclassification of mild steel welding fumes as a human carcinogen. Consequently, the HSE has strengthened its enforcement expectation for all welding fume, including mild steel welding and welding outdoors.

What does this mean for businesses?

General ventilation is no longer sufficient and changes are required with immediate effect. Previously welding fume extraction was not needed for outdoor welding or for short tasks such as tacking or minor repairs, however this is now no longer the case.

All businesses should ensure effective engineering controls are provided and correctly used to control fume arising from welding activities of any duration, including mild steel welding.

All exposure to any welding fume must be adequately controlled. Risk assessments should reflect the change to the expected control measures, and welders need to be suitably instructed and trained in the use of the controls. Where engineering control alone cannot control exposure, respiratory protection must be provided, for example in the form of a powered air respiratory system or a mask.

XR940A PAPR Welding Fume Respiratory Protection

Parweld’s XR940A Powered Air Purifying Respiratory System is ideal for situations where exposure risk still remains after other controls have been put in place, or for short-term or infrequent exposure such as outdoor welding.

It’s portable, compact and slim design offers comfortable, reliable protection, complete with a large view true colour welding helmet. Clever automatic control systems combined with three types of warning alarms ensure a safe, constant airflow for the operator.

Designed with the user in mind, the system features a simple one button control and clear user interface. The long life battery and the filter can be changed quickly and easily by hand. A contoured outer surface help to prevent snagging on other objects. Additional shoulder straps reduce the leverage effect that can cause PAPRs to feel heavy and unwieldy. Importantly, the operator can sit or lie down without obstruction to airflow.
“Regardless of duration, HSE will no longer accept any welding undertaken without any suitable exposure control measures in place, as there is no known level of safe exposure”
Scion Supply Ltd are a Parweld main distributor and have the XR940A in stock right now. Visit our on line shop to order your now!

Welding Cast Iron

Welding Cast Iron has quite a few potential pitfalls, but if done correctly, it’s not difficult.

Why is Welding Cast Iron problematic

The key reason why welding cast iron can be problematic is the high carbon content. During the welding process, this carbon migrates into the weld metal and/or the heat affected zone adjacent to the weld metal, causing elevated hardness/brittleness. This is how Cast Iron gets its reputation for post weld cracking.

Process for Welding Cast Iron

Gas Welding heats the Cast Iron slower than Arc based processes and the flame is lower temperature than an arc. This means Carbon migration is not normally a problem. Use of a proprietary Cast iron Gas Welding rod is important. The only real downsides to Gas Welding Cast Iron is the amount of heat needed if components are large. Gas Welding is also a slow process.

Arc/Stick Welding is, arguably, the best all-round process for Welding Cast Iron, provided the correct welding rods are used. Cast iron Welding Rods have a special Graphite rich flux, this graphite chemically ties up the Carbon in the Cast Iron, limiting migration into the weld metal and heat affected zone. There are two common types of Cast iron Welding Rod, Ferro-Nickel and Pure Nickel. Ferro-Nickel are typically 53% Steel and 47% Nickel. Ferro-Nickel Rods are cheaper than pure Nickel and are ideal for welding Cast Iron to Steel. Pure Nickel will produce a softer, more malleable weld deposit. I would advocate using Ferro-Nickel, unless the job specifically requires Pure Nickel.

Mig Welding is, in my opinion, not a great way to weld Cast Iron. Whilst there are specialist Flux Cored Wires available, unless you have a repeating application that you can create a procedure for, I would not advocate Mig Welding Cast iron.

Tig Welding is not considered a suitable process for Welding Cast Iron. An open arc process such as Tig offers no opportunity to mitigate Carbon migration.

Welding Techniques

Gas Welding – There are no specific techniques that need to be deployed.

Arc/Stick Welding – All of the following are important:

Prep the job with a ‘U’ shaped groove, avoid sharp corners as this can lead to heat build up which will exacerbate carbon migration.

Use the correct type of welding rod.
Ensure the component is AT LEAST at room temperature, adding a small amount of pre-heat will help, but you only need the component to be warm to the touch.
Limit the amount of welding done in one run. As a rule of thumb, do not put down a continuous run that has a length greater than 10x the diameter of the welding rod being used. Having said that, it’s ok to put down multiple runs in different parts of the component (see graphic in next item). Eg, if repairing a 300mm crack with a 3.2mm rod, you can weld a run of 32mm, then do another 32mm run in another part of the crack. Avoid letting the weld area get too hot, this is the purpose of short runs.
If you’re repairing crack, run a bead across each end of the crack to avoid the crack spreading further.

Keep the welding rod vertical, not at an angle, like you would for most stick welding.
Don’t expect to weld cast iron quickly, the key is to take you time and do it properly.

Overcoming the Pain of Weeding in the Garden!

Weeding is a real pain, right? Often this is a literal fact as well as a metaphorical one! Well I currently have access to a product I had not previously been aware of that makes weeding much less of a pain. I have a good stock at the moment, but these weeders are so well priced I expect them to sell out fairly quickly so you'd better get your order in quick.


Sievert are well known for being a world leading manufacturer specialising in high-quality heating tools for professionals. Sievert has been in business for more than 130 years and today works together with customers in more than 50 countries all over the world. Sievert's offering contains top-quality products for any type of soldering, brazing or heating task. Sievert strive for continuous innovation in the development of their products with new technologies and designs.

After quite literally years of fighting my own Infinity War with the weeds on my patio, using every method I could find, from weed killing chemicals to patio scrubbers to pressure washers, the Sievert Gardener was a bit of a break-through for me!

In fact, weed fighting with heat is nothing new. It has been used by professional gardeners for a long time. With this method weeds on patios, terraces and paved paths, kerbs and so on, can be treated in a non-toxic and environmentally friendly way.

You simply sweep the burner slowly about 5cm above the weeds. The plant should be heated - not burnt. The heating causes the cell walls in the plant to burst and the plant dies of drying out. A simple procedure to check that this has taken place is to press a leaf between the fingertips. This should leave a dark green fingerprint. After two to three days the leaves will have completely wilted and all you need to do is to sweep up and compost. The treatment is most effective in the Spring when the plants are small and have a limited resistance. The treatment must be repeated a couple of weeks apart during the planting season. A final treatment late in Autumn is also useful to destroy the seeds which will become next years weeds.

The Sievert Gardener is not suitable for use on lawns however and if you enjoy gardening, but want to save your back and knees a bit of strain, you might also be interested in this Garden Kneeler which combines the functions of a garden kneeler, stool and storage box in one. The Garden Kneeler allows you to kneel in cushioned comfort or turn it over to sit at the correct height for many gardening chores. Manufactured from a heavy-duty, impact resistant plastic frame, with an inset rubber seat and integral foam kneeler. The stool's cleverly designed legs have integrated hand grips, that serve as supporting arms to assist you when kneeling down or standing up again. The under seat storage compartment is useful for storing secateurs, gloves or other small hand tools. This dual-purpose kneeler is especially useful if the ground is wet or muddy, but it also has multiple uses around the home when working while sitting or kneeling is required. Check out both products in our Gardening Tool section at Scion Supply.

Launching our on-line shop

Screen shot from the new Scion website with on-line shopping facility

I have finally managed to find the time to finalise the Scion Supply on-line shop and making it activating payment methods and setting it to "live".

I really hope this will provide an opportunity for us to broaden our customer reach. We have worked hard to develop a product range that works over the last few years and these products are obviously now available to purchase on our website as well as in our Ebay store.

I have tried to maintain visual continuity through the two sites in terms of images. Our carefully selected range of products reflects our experience dealing with face-to-face engineers and mechanics, learning their preferences, what works and what does not work.

The main challenge with on-line stuff is getting the product uploaded. It can feel like something you are doing continually and it is a challenge to keep up with the day-to-day business tasks and get time to catalogue and upload product details. I've found doing a few a day helps.

In particular, I have a couple of new products I am selling on-line which are quite interesting. In this post I want to introduce you to this simple tool: PipeStrip.

PipeStrip is a really clever idea thought up to deal with a specific task. If you've ever been on site and had to strip paint from copper pipes you will know what a tough job it is. It usually involves a sharp blade, like a Stanley knife blade, and a lot of elbow grease!

Stripping is time consuming and hard work, so someone has had the clever idea of PipeStrip - a light-weight, handy tool specifically designed to make the stripping of paint from 15 & 22mm copper pipes easy.

To use, you simply place the curved blade of PipeStrip over the pipe at the point where you plan to make the cut. With your free hand, press the blade firmly into the paint so that it 'bites'. Maintaining pressure on the blade, push & pull PipeStrip along the pipe to clean about 5cm on either side of the central point, so that you strip approximately 10cm of pipe.

Turn PipeStrip as you work to clean the sides and back of the pipe - PipeStrip is flat enough to help you reach the back. It really is essential for any tool box!

If you visit the page in our on-line store and scroll through the pictures you will see a video we have uploaded about the tool, how handy it is and how to use it.
