I recently changed jobs, and one of the most remarkable things I've noticed right away is that almost all of the welders (there are four of them) use their Miller XMT 350 wrongly (???).
It gets used for stick, MIG/MAG and GTAW (TIG) welding.
Now, when they weld with MIG/MAG, the program selection switch stays on stick welding (!). One of them says the invertor respons better on parameter adjustment this way, the other welders just follow his practice.
I don't know anything on Miller invertors, however I've heard of welding machines using combined voltage/currect curves (both CC and CV in one setting, which changes at a certain trigger voltage).
What would be your opinion? I told them to use the correct setting as per the control switch. Which seems obviously logic to me. Could it be I'm wrong?
