A simple guide to choosing a Mig Welder. The article is written for those with little or no knowledge of Mig Welders.

Gas vs Gasless Mig Welding, which is best? is a conversation I have with customers on the phone on an almost daily basis. Gasless Mig Wire Firstly, let me clarify that “Gasless” Mig is not actually gasless.  There’s no such thing as gasless mig welding.  The weld pool has to be protected from the oxygen […]

What is Synergic Mig? The Dictionary definition of “Synergic” is: “Working Together Towards a Common End”. A Synergic Mig Welder where Welding Power (Voltage) and Wire Feed Speed are adjusted together, rather than separately, via a single Control. Most commonly, you pre program the machine with the size Mig Welding Wire being used, the type […]

Mig Welding is not a difficult process to master, but unless you get the basics right, it can be torturously frustrating! These 10 Tips to improve your Mig Welding help. I hope you found this blog article useful, if things work out well for you, please feel free to post some pictures of your achievements […]

Mig Welders are relatively simple pieces of equipment and are easy to use, the key is getting the machine set up correctly in the first place.  Key to this is the setting the wire feed speed correctly. A lot of smaller machines on the market, BlueMig BM-150T for example, have a helpful Chart, indicating the […]

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. As some of you may prefer to watch, rather than read, I’ve also […]

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 […]

What is the best gas for Mig welding mild steel is a frequent question I get asked on the phone. Unfortunately, there’s not a simple, straightforward answer as it rather depends on a number of factors! The three key factors are: I guess you can combine 1 & 2. Disposable Gas Cylinders If you’re using […]

What’s the right Gas Flow Rate for a Mig is a question we get asked a lot, but like many things in welding, there’s no definitive answer. The correct Gas Flow Rate for a Mig will depend on a number of factors: Having said all that, I understand you need a start point, so I’ve […]

I get asked “can you use the same gas for Mig and Tig” a LOT! Sadly, the answer is NO. Gas for Mig Welding Both Mig and Tig Welding require gas to protect the weld pool from Oxygen and often to cool the Torch but these are not the only functions it performs with Mig […]

Firstly, Mig Welding Aluminium with a general purpose Mig Welder is not ideal, a DIY type machine is even less suitable. The best type of machine to weld Aluminium with is an AC/DC Tig Welder Having said that, with the right set up, most Mig Welders can be used for welding aluminium (more or less), […]

Mig Wire Feed Problems can come in a range of guises, all of them annoying! Mechanical Mig Wire Feed Problems Mechanical problems with the Wire Feed system are by far the most common cause of issues with a Mig Welder! My philosophy with these is to start at the Wire Spool end and check through […]

For most things in Life, preparation is important, Weld Preparation is no exception. There are some fairly obvious weld preparations Where thicker metals are to be welded, a joint preparation may be needed. Butt Weld Preparation Typically, this would involve creating a ‘V’ preparation by grinding a chamfer onto each piece of the joint. A […]

I regularly get asked “How Much Wire is on a Mig Spool”, so I figured it was time I posted some figures 😀 0.6mm 0.8mm 1.0mm 1.2mm All of the figures are based on weighing a sample length of Mild Steel Mig Wire to calculate how much wire is on a Mig Spool. Figures for […]

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. As some of you may prefer to watch than read, I’ve also produced a video on this subject There are 3 key bits of data to Duty Cycle figures: Amps, […]
