RE: Torque Box Reinforcements

yeah, it was a mig. I dont think the guy really did that great of a job. I have southside machine lift bars, and running Nittos. I am somewhere close to 375hp, 460 tq. I have spray. but, I dont baby the car, I drive it pretty hard. and when it hook, it's like a rocket. well, you know Zach, you got slicks.

Yeah, shielding gas is a must...When I first started MIG welding, I didn't have shielding gas and I bought some flux core wire and got some decent welds... They were ugly as there was splatter. Flux core wire works OK if you're outside and have issues with a breeze -- I've used it outside on fences and stuff in the winter and it welds OK.

When I got my first taste of shielding gas & copper wire, man -- it was like night and day! The weld pool wasn't constantly getting blasted away by splattering. The welds were much better as I was getting better penetration due to the heat remaining concentrated at the location of the desired weld.

When welding with flux core wire you must switch the polls on the welder. Trust me, flux core can be just as good and in some cases better than a gas shield, it really depends on the application. I have made stuctual welds on 300 plus foot tall radio towers that pass mag particle and dye penitrant testing using flux core wire. As other have said though, the machine makes all the differance in the world, cheap welders are just junk when it comes to anything stuctural and are not any good for more than sheet metal (and that a stretch IMO).

Yeah, I know that you have to switch polarity and I did.

It still didn't make clean welds -- definitely not as clean as sheilding gas welds.

Edit:
And I said it was good for outdoors -- given a choice, I'm using shielding gas anywhere else. I was the one who made the comment about cheap welders.
