Reply:The question is not whether the welder will be strong enough; the question is will the .100 thick Toyota frame be strong enough to carry that weight??? I have built a LOT of Toyota bumpers, and I never go thicker than .125" material, with the exception of attachment tabs and tow hooks. The weight takes the nose down hard on those trucks, and is not necessary. I have dropped my Tacoma on it's nose from 5' up, and the .120 wall tube bumper took it like a champ.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.

Reply:It's all in the details, regular wire, CO2 mix? Is it ER70S6 or perhaps ER70S2? CO2 mixed with what and at what percentage? A Lincoln 255 has enough power to penetrate 1/4" steel just fine. The machine has the goods, it simply needs to be set up well. If you really want to penetrate steel with mig, study up on spray transfer mode.However, the project may not warrant steel this thick, as Rojodiablo has elaborated already.City of L.A.
