Welding subframe connecters w/ millermatic 135

66 stang, 289
global west subframt connecters, tubular weld-on
millermatic 135 110v/90amp flux-core wire welder

is it wise to attempt welding the subframes on myself? or should i take it somewhere that has a little bit bigger welder?

If you can weld laying on your back, you'll be fine. Remember that the "frame rails" on vintage Mustangs are pretty much just sheetmetal anyway, so try to concentrate your weld puddle about 70% on the subframe connector to make sure you get good penetration (always a good thing!) and you'll be fine.

a buddy of mine has an oil pit . .next best thing to a lift!

but you think that 110v will give sufficient penitration?

Yes, I do. I've only used a 110v wire-core welder once and was very impressed with it. I was in another shop doing a balancing job on a fan and when the time came to weld the weights on, all they had was a 110 mig. Not only did it do a nice job, but there was less spatter than I thought there would be without gas. The trick is to move slowly, weave slightly ( I make small "c's" when welding heavier stuff) and practice with similar gauge scraps before you do the real thing. Also, make very sure everything's clean by going over it with a grinder to remove any paint, undercoating, rust, crud, dog poop and whatever else may be stuck to the frame rails.

110V MIG will be fine. Wire brush the frame rail contact areas first for a solid weld. Spray with primer and paint afterwards.
