Sync 250, arc wonder under 50 amps AC

admin

I'm using 3/32 electrode, arc doesn't stabilize until I go over 50 amps AC, what can affect this situation? It sputters and wonders around.
Reply:Need more info.Tungsten type, stickout, gas and flow, arc length, tungsten shape, HF in continuous or start only, AC freq, joint type, etc.If youre welding a fillet with a balled 3/32 pure with a tranny and fixed 60 Hz AC, the arcs gonna be all over the place.Last edited by Drf255; 03-01-2013 at 04:40 AM.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
Reply:That's a big electrode for under 50ABuy American, or don't whine when you end up on the bread line.
Reply:Try increasing your HF.  If you have the option,  dial up some starting amperage.  But like the others said, balled 3/32 tungsten in a transformer is going to take all of 50A to stablize an arc.Syncrowave 300Maxtron 450, S-52E, 30A
