Amp. Output on inverter welder

admin

I have 2 inverter welders, both are 200 amp. Machines. If I set both welders at the same amperage,120amps and use the same electrode,electrode holder,cable and ground clamp with cable. The welder with the digital readout welds much colder (about 20/25 amps less) . Is there a way I can check the amp. Output on each machine. The digital read out machine is the one that welds cold set at the same amp. And is there a way to calibrate that machine
Reply:clamp style amp meter, that reads true RMS ?
Reply:I don't think any two welders, even the same make and model,weld exactly the same when set the same. I consider the indicator a reference point. It's up to the weldor to find the sweet spot.                                               MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
