Quick question.... we have a millermatic 130 at work and use it for
regular steel welding and some stainless welding - and it works fine.
Following the advice of the welding shop, using Argon/CO2 mix for the
gas and running at 20 cu ft on the regulator. Works good and getting
good welds on both regular steel and the stainless. This welder was
"in place" when I started working there and they had spools of copper
coated steel, stainless and also aluminum. I have tried the aluminum
on a couple of different occasions - without any success. My
questions would be:
1. Can this welder actually weld aluminum?
2. Would the gas or the liner have to be changed in order to weld AL?
3. If it is capable, and since there is a variable speed on the wire
feed and 4 settings for heat, what would be the recommended settings?
4. Any out - of - the - ordinary prep work have to be done (like
cleaning to shiney and pre-fluxing with some kind of paste?
I've tried (as mentioned) without success, but I can place a nice blob
of what looks like overheated aluminum on top of the piece to be
welded, but it certainly is no "weld" in any sense of the term. Any
input on this would be appreciated.
