What to consider when choosing a TIG welder?

Updated: Aug 23

Trying to find the right TIG welder for your needs can be a stress-inducing process. We want to help you breeze through the decision and get straight to what you are good at, welding.


What is TIG Welding?

TIG stands for tungsten inert gas and is a popular arc welding process for smooth applications. It is seen as one of the toughest processes to master. Electric arc burns between the non-melting tungsten electrode and the workpiece. The arc is very intense and can be very easily controlled. A separately supplied argon shielding gas protects the arc and the welding zone from the atmosphere. Filler metals can be fed by hand or with a special cold wire feed if necessary. Steel, stainless steel, copper, titanium, etc are welded with direct current. The electrode is connected to the negative pole and ground to a point. Aluminium, magnesium and their alloys should only be welded with alternating current to break open their oxide skin. The electrode is blunt. During welding, it can assume a round or crowned shape. With modern inverter power sources, a pointed tungsten electrode can also be used.


Advantages of TIG Welding

TIG welding allows good control over the arc enabling very comfortable and clean working. The low oxidisation of the workpiece, small welding zone, omission of fluxing agents and non-spattering arc ensure clean, precise seams with no slag inclusions and no reworking.




Selecting the perfect TIG welder is often a stressful task. Due to cost, market-leading brands and new models create a manic list of potential machines.


What's within your budget?

Looking for a new machine, the price often comes into it. Knowing your budget can help narrow down the machine that will fit your needs. Higher price tends to indicate high-quality equipment. Although if you have a limited budget you can find a welder that is effective for your applications.


What metals are you welding?

TIG welders often allow welds of more metals and alloys than other

welding processes. Depending on the metals you are using will also impact the tungsten you will need so keep that in mind.


How do I know which to use AC/DC or DC?

DC welding machine is suitable for commonly used metals such as mild steel and stainless steel. Whereas using AC/DC allows you to switch the current type depending on the metal you are using. If you are welding aluminium AC/DC machine is the one for you.


What is Pulse welding?

Pulse welding is also an important part of choosing a tig welder that suits your needs. Pulse welding is the process of welding that alternates between a high and low current, this is beneficial due to a reduction in overall heat.


Should I use a TIG pedal for my welding?

Using a foot pedal allows you to have more control with accuracy and quality while welding. Some people may see their flaws within finding them uncomfortable to work with.
