Old trick folks. Got this from a Lincoln rep one day back in the 90's.Drill a contact tip out to accept a piece of tungsten, I used 1/16 tungsten. In the side of the contact tip drill and thread a hole for a small set screw ( used to hold the tungsten in the tip ).Max the wire feed setting and then use the voltage to adjust arc length. Ofc change your Ar/CO2 mix to straight argon or helium.Break off tungsten to a length that will fit fully into contact tip and extend past Mig nozzle 3/8 or so. Scratch start the arc ofc.Keep in mind duty cycle of machine. This trick is for small tig welds if you have a Mig.Have fun
Reply:Sorry to say, but this is completely wrong. Everything is wrong starting with the fact that mig are CV, constant voltage, welders and tig and stick machines are CC, constant current, welders.
Reply:I have an old toaster oven I took apart.... I took the thin wire that heats up and wrapped it around a long piece of tungsten then I plugged it into a 220v socket... I am able to lay down a stack of dimes on thin stainless. oh, scratch start only.PS, if your hand gets hot just pour some beer on it.Miller 211Hypertherm PM 451961 Lincoln Idealarc 250HTP 221 True Wisdom only comes from Pain.

I rarely supply any info concerning welding or metallurgy that one might "say" is completely wrong ....... Guess you haven't used a dual wire aluminum weld procedure where the 2nd trailer wire is put in using AC current supplied by a CC source...I will restate... This trick was shown to me by a Lincoln rep back in 1997. Works awesome!!!
Reply:Probably could rig up a stud welder from a CV machine. Do you find this completely wrong? Does your Miller 350P disagree? Why wouldn't you use a Cobra? Way better then any old Miller 😄Poking fun here pal. Don't diss what you don't know.You can use a CC machine for a power source for Mig.You can use a CV machine for Tig and stick also.Enjoy |
