Yup, arc wouldn't initiate through cooling flux at lower amperage. Since making vid it's become clear the inverters I use maintain arc over a much larger gap than the machines rapucuf uses, they seem happier running continuous low amperage. I think a cheap inverter would do dab technique better, esp. in conjunction with the right flavor of 6013.

@@Octopusbeak True. I can definitely confirm that the flavor of 6013 plays a major role from my experience. Some just want to be ran as hot as they can go, otherwise the slag overruns the rod despite relatively aggressive drag angles and arc force. That was my experience with Gys electrodes. Some run smooth as silk, such as Adria R 6013 from a local manufacturer Elektroda Zagreb. I would say that 6013 are in that regard more finicky than 7018s and 6010s. The Lincolns seem to run quite well?

@@Mirage2000H After welding a bunch more with lincoln 6013 and watching more rapucuf, I would say the lincoln rods are not as forgiving as the nikko rd-460 he uses for dab technique. Slag sticks more, restarts harder with lincoln rods. But they might run better with straight low amperage dragging rod. Been welding lots of 16 ga with 3/32 6010 which is faster and more reliable. I still use 6013 to fill a gap or hole.

@@Octopusbeak can you do a video on 6010 on thin stuff please?

@@pkplexing would 6011 on thin material be okay? it's far easier (read: better welds). I wouldn't mind making a video though
