So I've got everything for my winch cut and figured out, only I am working with a miller 115V mig welder. Even if I double and triple the weld beads I am told it will not hold 10,000 pounds of pulling force and that I should Arc weld everything. 1/4 inch thick square tubing. What are your thoughts?
turn that buzz box up as hot as it will go and burn it in. run triple pases and linger at all the high stress points. you will not be able to burn through that thick of metal so go real slow! i think you will be fine.

Fishman is right. You won't burn through 1/4 inch metal with your welder. What I would do is grind a bevel in the metal to assure I get good penetration all the way around. Take your time and do a good job.
What model Miller? With a good bevel, and multiple passes, you SHOULD be ok, but if it's in question, get someone with a bigger welder to do it. That is alot of stress on it.
I teach welding and my sugestion is to tack it up and have it welded with a 220 machine and I would still have the person weld atleast 3 passes so that it would get good penatration mig welding will be fine but I would weld it with a 7018 on a stick welder .
Although it is possible to weld everything with my welder, there is still doubt that I will have with it, so I'm going to tack it and get someone to arc weld everything. Thank you for the suggestions it helped me decide to go the extra distance and do it right. Thank you.
I would HIGHLY recommend what the others are saying. Tack it and find a 220V or 440V welder to do the finish work. Most towns have a local weld/repair shop that may only charge $20 since you did all the prep work.
My experience on this issue comes welding a "pull" ring for my grandpa's International 504 tractor (row crop not utility). Anyway, the tractor has mounting holes on the front for weights. I got a piece of 1/2" plate and drilled holes for mounting to frame, 4 each side. I then used a piece of 1/2 x 2.5" bar stock bent into a rough V-shape. Put a 10,000 pound D-ring in and welded it at work with 440V 3 phase Miller running 0.052 wire. I triple passed both ends of the bar stock. Needless to say, the welds broke one day trying to pull the tractor out of the mud with the neighbors MFWD 8430.
Moral of the story, tack it and let a larger machine do the welding.

I got someone with a 240 amp stick who is taking the job. I told him I want around 10K pulling force he says it should hold up.
