Another thread got me to thinking about this. Somebody implied that most of
the MFGs just want to sell you a new power supply rather than tell you how
to do with what you have.
I've got a Miller 212 and I can weld aluminum with it (spool gun), but it's
a struggle. Short welds that I can do in one quick pass (1" bead in 1/8"
sheet for example) aren't too bad, but more than that is difficult at best
for me. I have to stitch and fill back and forth. For thin steel I can
often just make little short quick welds and get a nice bead that looks like
a TIG weld to the uninitiated. Kind of a really really slow pulse weld.
LOL. For aluminum that doesn't seem to be practical due to wire tip
globbing and the resulting flash back. Its best to make continuous welds
where I can and clip the tip of the wire before I pull the trigger nearly
So, is there a pulse welder adaptor of some kind I could use with my 212
power supply. Its my understanding that most pulsers use a variation of a
How about something that shorts the gas and feed relays inputs, and pulses
the trigger button input? I know. I know. It's a shade tree hack, but
could it work?
