I just got some Lincoln Electric 6010 ++++ rods about 5lbs from the local welding shop they came in a 50lb tin and I tried welding with them yesterday and my arc was terminating while I was welding. I had an 1/8 in rod at 130 amps DCEP.
I am running a transformer machine Vulcan Commander AC DC 225/150. And its my rod that quits burning after a few seconds I'm trying to keep as short of an arc length as I can. I didn't clean the metal I was working on cause I was just running beads on it to see how it welds
classic symptom of a machine that does not have enough arc voltage to keep the 6010 rod lit. Unless you've already done it successfully before. But otherwise if it snuffs out with just the tiniest increase in arc length, bingo you found a machine that can't run 6010.
For a nominal extra cost, my Dynasty runs em just fine.Oscar wrote:classic symptom of a machine that does not have enough arc voltage to keep the 6010 rod lit.

sounds like OCV is to low and probably the transformer size is to small which gives low welding voltage.9rpcrowe wrote:I am running a transformer machine Vulcan Commander AC DC 225/150.

however one thing to check is the voltage of your mains power. transformer machines require good mains voltage and decent sized power leads and mains circuits.
good inverters will self regulate to a degree so they are not so susceptible to mains voltage drops.
just another reason why new transformer machines are rare these days.
tweak it until it breaks
