Took on a project for a neighbor.
This Mac tools (Miller) 140 Plus will sparkle when trigger is pulled, but no weld output.
It has OCV readings in the correct ranges (although tap 1 and 4 are reversed for some reason). OCV does not change when trying to weld since there is no weld output.
I have not tested a mig before and it's puzzling me.
The back of the voltage switch should have power coming in one wire and going out individually on one of 4 wires right?
I must be testing something wrong because I don't find any power coming in.
Contactor engages briskly, but I am not seeing any power leaving it when engaged.
Could someone please give me a simple run-down on testing correctly so I can see if I'm doing it right?
Here is the manual:
