recently started tig welding about a month ago. been having problems with my tungstens becoming contaminated every time i lay a bead down. sounds and looks i am mig welding. using a lincoln precision 225 machine with straight argon.
mostly been welding chrome moly and mild steel. pretty sure my metal prep is in par, as i used a flapper wheel, scotch brite. i wipe metal, tungsten, and filler rod with acetone prior to welding. tried different tungstens, different argon flow, ground positions.not sure what i am doing wrong here. it seems to me that it appears to be some form of contamination.
one thing i have noticed is my arcs just do not look right.
thanks

Using it for grinding tungsten only. If used for grinding other materials, the other material will embed itself into the grinding stone, and then embed itself into the tungsten from the stone the next time you grind tungsten.rickbreezy wrote:What makes a grinder "dedicated"?

Is it kinda sputtering or spitting with alot of black soot? If its somethin like that then you either have to low gas flow or bad gas.
Signature? Who needs a F***ing signature?

no black soot. thought an indication of lack of gas, was inside of nozzle turning yellow, which i experienced earlier along.
one thing i do notice, every time i tack weld, i have a ring of what appears to be rust color around every tack.
