I have a 30A spool gun on my 250.
I will be welding 1/8th to 3/16th and id like to know what i can do to minimze spatter. I seem to be getting lots of carbon and white residue on my welds as well as a brilliant spark show. The weld arc doesnt seem to be hissing as it should, its more a of a crackle/hiss.
parameters i am roughly following to date include 30 degree tip angle and a push path as recommended for mig'n AL.
material is all 5000 (5086) series with 5356 0.030 filler wire.
Oh yeah and I read in another post somewhere about holding the trigger and turning on the main power on the mm250. I didnt get what was being described so i tried it. What i found was that the numbers changed in the dispaly and the gun fed at a differerent rate. Still confused. Too much on my little mind. would someone care to explain what i did? thanks.
Thanks Guys, any info or suggestions would be well received.
