doing a metric ton of scratch start this and next week, hundreds and hundreds of but and fillet welds .75" x 16 gauge HRS.
doing the strike a match routine seems to work best for me, anything else and i get stuck to the work piece and fowl the tungsten way way too fast. but even with this technique i'm getting maybe 16 joints before re-dress.
it's working fine, all things considered, but wondering if anyone has any tips on getting better arc start without fouling or getting stuck. i've heard about guys striking off of the rod itself but i can't wrap my brain around that one.
I've only ever dabbled in scratch start as my old back up tig, may she rest in piece, had 4t controls for the thumb torch... which i got spoiled by.
on this job i'm running my later model sync 250, 1/16" tungsten (red), standard cup/collet body, running around 75 amps, HF off, gas flow at around 20 or so.
