When I got my Primeweld TIG 225X, it came with both a foot pedal and a finger trigger. I had always used the foot pedal up until recently. I was working on a project and wanted to place a few tacks, but found it awkward to reach the foot pedal from where I was. I decided to install the finger trigger on the torch and give it a try. I also try to explain 2T vs 4T and how the affected controls on the machine are used.
But don’t tell the cops! 😉
