[Towertalk] Slightly off subject ? - MIG welder

[wa2bpe@infoblvd.net (WA2BPE)]

Gentlemen:

This is slightly off subject - or is it(?) - since towers/antennas often
require welding.

I am looking for the circuit diagram for a NAPA 83-315 MIG welder (or
similar).  My mechanic (who also does some tower/antenna welding for me)
is having a problem with his unit and the documention is "lost".  Any
assistance or pointing me to an information source would be appreciated.

Tnx & 73,

Tom - WA2BPE
