Ok, i want to do the rock slider replacement of bad rockers with the square tubing. and patch a couple of rust holes in the floor board. I plan on possibly making a front and rear bumper in the future but i was curious on what type and/or models would u recommend. I only want to spend 300.00-350.00 at the most on welder and would prefer to stay in the 110v range. Any advice would be appreciated.
