Scratch start TIG is still being used a lot for high quality pipe welds. Its a very simple and basic Tig welding system that works very well for pipe welding. The main drawbacks are …no remote amperage control, and not being able to shield the weld where you terminate the arc. This video shows a few tips and a diy foot switch.

Every miller I've ever used has had the most unreliable HF start always in for an expensive repair so I don't bother anymore I just use lift or scatch..
Add me to the list of people who would like details on your on off foot pedal
That foot pedal is a great idea. Do you have a video on making that?
Would starting arc on carbon rod and moving quick to material work?
Scratch start. Let me step on my homemade foot pedal. Uhmmmm. Ok. Let me show you how to use my arm to throw an arrow through a deer. First I take this piece of wood with a string attached to it…………..
Hi. Can I use tungsten 2% thoriated on my Miller 150 stl? Thank
I had to learn how to scratch start with my little 140 amp everlast until I got one with high frequency start.
Can u make video of foot pedal
Hey Jodie (or anybody for that matter), with a foot pedal setup like you have could that be used to initiate the arc too like in lift start? Ya know, for the sake of a clean tungsten? I'm thinking touch the tungsten to work piece, complete the circuit with the pedal, then lift? Or would it just stick? Too much amperage? I want to get into scratch start but I feel like a noob such as myself would just be spending all my time grinding tungstens and I'm trying to think of ways to make things a lil easier/cleaner…thanks!
Thanks helped me a lot, it had been many many years since i had done any tig welding. I had the situation where it just wasn’t getting a nice flow going and took a while to pool, it was my angle and ark distance. I just purchased a similar machine for the shed , very capable unit. Thanks agian
