welding question

skid2010-08-08 12:18:50 +0000 #1
I have a mig welder 120volt and have done lots of steel welding with it and tonight i'm going to finally try welding aluminum with it, is there any welders out there that may have a few tips before i start?

I've burnt many a mile of wire and several hundred pounds of 7018's but never aluminum.

you just need argon gas. It is way easier to TIG aluminum Then MIG aluminum. Actually I have never migged aluminun and should only comment on TIGging aluminum. I'll ask at work tommorrow.

i think you need a spool gun for aluminum.

I've heard that a spool gun is needed also. I looked into MIGing aluminum before, but the spool guns are NOT cheap from what i remember. You could probably buy a TIG welder for not much more than they want for those spools.

Yeah you'll need the alm setup w/ alm wire. Is your welder a dual feed or are you just planning on swapping the spool?

U actually dnt have to have a spool gun u can use a regular type welder like u have it is just a pain bc u have to keep the hose almost perfectly straight are it will back all up on u an have a big ball of wire in the machine... True tiging aluminum is the way to go that is how we do it at work but hard to get a setup like that at your house. my suggestion would be to look in to a spool gun thats the way to go for your home shop aluminum...
