Migmatic 273

admin

I have recently acquired two used Miller Migmatic 273 mig welders. They are supposedly both functional, but I haven't had time to test them yet.

The first unit seems to have all the original parts and wires still factory tied together. But I noticed that the board in the front with an LED display board is missing. I assume that the board was removed for some odd reason. Another thing that stood out was the broken contactor. Someone must have pulled on the power cable a little too hard and broke the contactor case.The first unit:

Reply:The second unit seems to have had the control board replaced with an aftermarket one. The cables are all a mess and the potentiometer for "Spot Weld Timer" has its wires cut. However, the LED display board is there.The second unit:



Any comment or recommendation by anyone using this welder would be welcome. I hope I find some time to test both units over the weekend.
