I've finally decided to bite the bullet and add frame stiffeners. I have the mid and rear stiffeners from JCR Offroad. My question is the technique of welding the 3/16s stiffeners to the thinner unibody "frame". I'm not the best welder but do ok. I have a Miller 100 amp and a Forney 140 amp migs. I'll use the Forney. I assume that I should start the arc on the thicker stiffeners and carry onto the frame. Is that a correct assumption? Also the stiffeners have holes for plug welding. I've watched several videos and some weld the entire diameter of the holes others just parts of it. Also I've seen conflicting info about welding the top and bottom edges of the stiffeners and using weld through primer. Can y'all help me with some guidance?
