weld only 1-2" at a time (tnt reccomends 1")

bounce around from one side to the other, front to back allowing plenty of time for the welds to cool.

If you don't theres a good chance you will warp the housing and you will have a useless truss and axle.


that and measure as many times as you can then burn it home. nothing sucks welding something down and realizing after that your coil buckets are bowed forward and you cant get you shock bushings on the studs because of the angle they are at

Tack it first. Test fit... make adjustments. Then burn them in. Take your time, and use proper technique. Not sure what kind of welder you are using, but I would be using my lincoln stick, and I would weld first using 6010, then switch to 7018 for the "hot" pass

stick welding is arc welding. mig welding involves a "gun" an is wire fed. if you are not used to welding, the mig is the easiest to learn. you could learn to mig descently in about 2 hrs or less. personally i would mig weld the truss if i were you.

Yes it is easier to MIG, but I perfer to use my "stick welder/arc welder". It is what I learned to weld on. I can make just as pretty and structual sound welds with that as I can with a "MIG", I personally feel you can control the penetration better, and with the correct rod choice a stronger weld. It does waste more electrode, then a MIG. IT is also easier to store various filler metals(rods), for different materials, and thicknesses.


TIG Welding is Tungsten Inert gas welding. Basically this is the ultimate in control when it comes to welding. You can really control the Heat affected zone with this, and how much penetration you get.
