1 – Tig Torch Polarity If you’re welding in DC mode (Steel, Stainless etc), ensure your torch is plugged into the Negative (-) side of your machine’s output. Plugging the torch into the Positive (+) side will cause the Tungsten Electrode to burn away really quickly. 2 – Tig Torch Hold Make sure you’re in […]

Tig Welders are a great asset for the right applications, but before jumping in to buy one, it’s worth learning a bit about the basics. TIG, stands for Tungsten Inert Gas You’ve probably also come accross GTAW which stands for Gas Tungsten Arc Welding. This term is used by the Americans, but the process is […]

Simply put, NO, you can’t Tig weld without Gas! Gas is required to protect both the Tungsten Electrode and the weld pool from Oxygen. Most Tig Welder torches are also cooled by the gas, so not using gas would risk burning out the Torch. It’s theoretically possible to use a Flux, in the same way […]

The choice of type and diameter of Tungsten Tig Electrodes is important as it’s from the Tungsten Tig Electrode that the Arc is struck. Also important is how the Tungsten Tig Electrode is sharpened when used for DC Tig Welding. Types of Tungsten Tig Electrode Tungsten Tig Electrodes are colour coded, making them easy to […]

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 […]

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 […]

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, […]
