Torontofred Themeter you're using is either an average AC meter or True RMS. In either, the wave form must be sine wave. If you have any other, then you won't be reading it correctly.
Svar 2020-12-24 10:49:13BG401544916 @Torontofred Canyou explain about what you are talking. About AC or DC current. Thank you.
Svar 2020-12-25 02:07:03Gerard Vaughan The output is said to be d.c. Ate you saying the makers used an instantaneous peak reading ammeter ? But in any case we don't know if the current is time varying at 100-120 cps. It might be smooth.

So you reckon the thing supplies full wave rect unsmoothed dc, and the makers are quoting the instantaneous peak current ?
That's still a ssttreeeech !
Pot202 Happy Birthday and Merry Christmas. I would like you to help me fix the machine at 250 amps. With some photo maybe. Thank you very much.
Svar 2020-12-26 00:26:28Garabonczias Dear All! Some important points: (1) The current should be DC (in AC the arc would disappear 100 times in a second...!). (2) That DC current is never smooth during welding, as contact is bad, arc has haunting (continously changing) resistance

One more thing: the clamp meter should be TRMS one, with high Crest Factor. Than it will show a better value. BUT, the current waveform is so distorted, you cannot expect a really good meaured value.
Best regards
Mieciu HiMarek - could you explain how to adjust display to show real current values?
