TIG Lift Arc Start Current

instead of lift arc. what about high freqency welders.

I have a WPS, used for Millers. I'll have to look for it, and send the info thats relavant.

Which would be the setting for the machine, material, and gas settings and thickness, as well as tungstens and cup sizes

Hello phoenix911 Thanks for your reply.

I am not interested in the welding current per see or HF function, therefore the cups and tungstens are not of primary interest.

What I need is the value of current while the electrode is shorted to the work prior to lifting? also the open circuit voltage prior to touching the work only in lift Tig mode.

The tungsten size might have a small bearing on these values but do not expect it to be very large. The other item that could significantly effect this reading is the setting of the weld control [ max welding current] in low amps position. however I did not want to complicate the question so thought I would leave this until I had some results to work on. However at this stage I do not see many answers coming forward as what I am looking for has to be measured probably a lot of welding operators do not have the instruments to check this.

Hopefully a few might do this for me.

Thanks Garth

garth,

For something like this, you have consulted the manufacturers of welders.

I see this where they would have the instruments for doing these test during development of the welders.
