[AT] Mig welders for antique tractor sheet metal work??

[Billy Hood]

The weakest link in the old red Lincoln buzz boxes is the cooling fan.  If it does not run, you will burn up something.  And it is a 220 volt fan and hard to find a replacement out of the junk box.  I have a 225 AC at my son's shop now that we got free because of that--burned up the amperage swithch.  I had a cooling fan out of an old AC/DC that the diodes went out in and bought a new switch for $46 and had cheap reserve welder.  It is a good thing to check for the cooling fan running on any welder.  I have a 300 amp ESAB 3 phase MIG that I got because of the same malady.  Fitted a replacement and replaced the switch that had melted and cheap reliable welder.  I have also had a fan go out on a Lincoln SP 175 MIG that I used to put a lot of hours on.  It has since been replaced, but was a good machine.

  One thing I learned the hard way....  When you turn on one of these
  Lincolns, always pause and listen for the FAN.  I have a real problem with
  dirt dobbers.  A few years ago the finally nested in the welder fan and I
  didn't notice it.  This was a 70's era 225 and the switch shaft is plastic
  or some "bakelite" type material.  Without the fan, the heat fused the
  switch.  I didn't know anything was wrong until I needed to change amperage.

  I think a replacement switch was $50, but there are at least 2 wires to
  solder for each amperage setting and some of them are pretty heavy.  I fixed
  it and they all work.
