How to set up and use the TIG foot pedal

The foot pedal or foot controller can be used to control the current intensity of the welder while welding. Weld overheating? Release the pedal and lower the amplifier to allow the weld to cool. The foot pedal gives you full control without having to stop and readjust during the weld.

They should only be used when TIG welding, since stick welding uses welding pliers instead of a torch and the current intensity of the MIG depends on the wire feed speed. This is no big deal considering that TIG usually requires more control over low amperage on thin metals.

 

Why do I need a foot pedal?

TIG welding can often seem quite daunting at first. Especially if you have a dedicated TIG welding machine with a hundred little lights, options and settings.

Okay, not that many, but the little pyramid of welding parameters on your TIG welder can be overwhelming.

If TIG is already in the minority, why on earth would you use a foot pedal to add another variable to the mix?

Since the intermediate weld can be adjusted instead of always remaining stationary, the foot controller gives additional control over the amperage (heat) of the weld. The added control means better welds. Plus, it can be more comfortable.

The comfort level of the welder can change the outcome of the weld. It is much easier to hold the pedal with your foot than to keep your finger on the button.
