View Full Version : Alum mig 187

02-12-2017, 03:14 PM
I was wanting to see if anyone is running a 187 or any MIG with a plastic liner doing aluminum? I have a oil pan about 1/4 inch thats cracked and i need to weld it. I dont have a TIG or know anyone with a TIG so i was going to use my 187. I know you can do it but i just wanted to know if you can get good results. Im sure ill have to preheat it alittle with it being 1/4 cast aluminum. Post some pics!

If you have oxy acetylene, braze it.

Forget it. Cast alum ? You'll play hell getting it clean enough and you'll wish you never put that roll of AL in that Hobart..LOL.
Its a byatch. Snatch the oan, get it tanked and bead blasted inside and go get it tigged.Any motorcycle shop will know a tig guy and a tank guy to clean that pan up. They very well may have it in house ( Harley guys) Or buy a damn steel oil pan (if available).

No O/A no motorcycle shops around me. and i dont know anyone with a tig so mig is about the only way i can go.

In that case. GO FOR IT. It's quite an experience. You want that whip as straight as you can get it heading towards the part.Like a pool stick !Get to roller tension just right ....light squeeze--magnifying glass as the wire leaves the roller and enters the whip.
Now. After that , if you enjoy pain enough to try again....... call HTP to make you a teflon lined 6 foot whip and have a go at it one more time !
Pull the pan, go to the post office, and send it out

You already have a bottle of Argon?

That is going to add to the cost of this experience too.

For the record. Idid/ tried to run AL through a Lincoln 180C about 5 years ago.I managed to do about 15 window frames with about 12 bird nests and 1/2 a dozen tips and then ordered a spool gun.....that I tried out and never used again.I sold that machine to the guy I was doing these window frames for and he put a 5-6 foot custom whip on it and used it for quite some time. He liked that better than the spool gun.I never got a chance to run it with the custom whip. A couple years later he dumped that whole rig and now runs a Square Wave(as we should have done day one)
