MTS250S Weld Cast Iron and Aluim.

[Kempy]

I weld the broken cast iron cannon that someone dropped off a back of a truck then brought it to me to fix with a little love and care I got it back together used my MTS250S in Tig mode and welded it with Cronatron Cast Iron welding rod.

All welded and painted and the customer not to be found phone out of order I might have a new garden toy.

Hope the guy shows up (with cash) to pick up. There's a lot of Civil War history around here, and every now and again you see a cannon in a front yard.

What parts were aluminum and what parts cast iron?

The truck is aluminum and the cannon is cast iron.

Kempy, that aluminum looks like you welded it a bit cold. Was that in spray mode? That's the only way to MIG aluminum...or it won't hold up.

It was close to spray mode but when I was test it on the same material 1/2 on 1/8 inch it blow thru about 2/3 of the way down the hinge but look good up to that point, so I had to turn it down even turning it down the weld did blow out at the top because it was to hot, welding across the top part of the hinge the pressure inside got to high it was seal to keep water out I should have drilled a hole and weld it up later live and learn. Maybe I should have gone to .030 wire not .035.

The cannon was made just for looks and was never able to fire, right ? Did you ever consider grinding the welds down and trying to match the cast finish ?

Well I did a little research and most of the Mig aluminum thick to thin use Helium mix. So I mixed a 50/50 argon helium and tried it. That is the way to go with a little practice I think it will weld nicely. I used it in SYN spool mode and up the volts by 1.5 I read on Miller site. The heat is more on the weld with the Helium mix then with 100% argon just need hot start and pulse would be nice also, but that a lot of money buying a pules welder for aluminum from Lincoln or Miller or ???? I will just wait some day Everlast will come out with one I hope.

I used my MTS250S and spool gun to welding out in the rain and wind to fix this dump truck aluminum box with a third hinge in the middle to stop it from pushing out. The factory hinge was weld with a Miller 350P at $8000.00 and me with my Everlast MTS250S and spool gun with no pulse no hot start and the truck was outside not inside. The customer was happy and thought I look the same, he is not a welder. With more practice I thing I can get it close.
