What does Duty Cycle mean in Welding

Thursday, 17th May 2018

This is a common question.  Essentially, Duty Cycle is a measure of how long a welder will operate for before it overheats and cuts out. If you’re more of a Watcher than a Reader, you may prefer a Video Explanation There are 3 key bits of data to Duty Cycle figures: Amps, a Percentage Figure […]

Oxy Acetylene Flame

Tuesday, 24th April 2018

An Oxy Acetylene Flame will fall loosely into one of three types: Neutral, Oxidising and Carburising Neutral Oxy Acetylene Flame A Neutral flame is achieved when there are equal amounts of Oxygen and Acetylene. A Neutral Flame is so named because it has no chemical effect on the molten metal. Key characteristics of a Neutral […]

Silver Solder & Braze

Wednesday, 18th April 2018

Silver Solder & Braze are both products used with either an Oxy Acetylene Torch or Oxy Propane Torch. Silver Solder & Braze, what’s the difference? For me, the key difference is how they work on the joint. Silver Solder Silver Solder is more fluid than Braze and works by being drawn into the joint by […]

Propane

Friday, 6th April 2018

Is Propane any good? YES! It’s a great gas! It’s versatile Can be used with or without Oxygen (with correct Torch) It’s cheap, compared to Acetylene It’s readily available It’s available without Cylinder Rental The only real downside to Propane is that you can’t weld with it. Pretty much everything else can be done. With […]

Welding Cast Iron

Friday, 16th March 2018

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 […]

Setting up Oxy Acetylene Kit

Friday, 2nd March 2018

Setting up Oxy Acetylene Kit is not rocket science, but it is important to do it correctly. Setting up Oxy Acetylene Kit – the basics Oxy Acetylene fittings consist of a concave Female sealing face on one component and a Male ball shaped sealing face on the other.  A Nut clamps these faces together to […]

Welding Stainless Steel

Friday, 23rd February 2018

Welding Stainless Steel is no big deal.  As long as you use a suitable welding rod or wire for the type of Stainless Steel you intend welding, all should be pretty straight forward. Welding Stainless Steel is not vastly different to welding Mild Steel, which is why I say it’s no big deal, however, there […]

Tuesday, 20th February 2018

What is Roller Tension? Mig Welder Wire Feed Roller Tension is how tightly the Rollers Grip the Mig Welding Wire to feed through the Mig Welders feed mechanism and torch.  Feed Roller Tension is one of the more important mig welder settings. If you’re more of a watcher than a reader, I’ve produced a video […]

Mig Welding Gas

Tuesday, 20th February 2018

Mig Welding Gas is required because it’s essential to keep Oxygen from the weld pool. Shielding gas does this by replacing the Oxygen containing air that’s all around the weld pool. Categories of Mig Welding Gas Mig Welding Gas falls into two basic categories, “Inert” & “Active”. Inert means the gas has no effect on the […]

Welding Aluminium

Thursday, 25th January 2018

Welding Aluminium has often been seen as a bit of a dark art that’s the preserve of the seasoned professional welder.  But is that still the case? Welding Aluminium is certainly not as straightforward as welding materials like Mild Steel and Stainless Steel, but modern methods and equipment are making the welding of Aluminium less […]
