notch welding questions

[The Fab Shack]

Flux core burns hotter then using gas. Get a wire wheel attachment for a drill and make sure you clean your beads after you lay them. But if you lay down a bead and get flux inside of it, it will be weak at that point.

a Lincoln 145 will weld anything you stick on your truck without any worries (just make sure you prep, prep and prep.. i.e. clean the scale off the metal, bevel your edges). You dont need .250 thick stuff anyways. Are you building a trophy truck? no. You will be fine using .120 and .188 stuff on your trucks, which is all that we should be using. No reason to add weight that is adding nothing.

Here is what a 110 will do if you know how to weld. My 220 is packed up as i'm moving shops, but my backhalf is .120 wall 2x3

.120 - .180 maybe fine, but the bolt in C notches are made from thicker material, thus the OP's question.
