I've got an accessory for my air hammer that puts a stepped-down flange on the edge of a hole. This allows a flush patch to overlap the hole and provides a much stronger method of installing it than a simple butt weld. Jerry
The murder victim was drowned in a bathtub full of Rice Krispies and milk. The coroner blamed the crime on a cereal killer!

The only welder I have is an oxy-acetylene rig, and two weeks ago I needed to rent an arc welder. The place I normally go had rented all their units so I decided to rent one of the Lincoln wire-feed units Home Depot has out of curiosity (.030 or .035 size internal flux wire). Once I got the feel for it and got the feed rate and amperage balanced, the thing did a surprisingly good job...particularly for a 120 volt unit. Good penetration. I used a multi-pass approach One piece was 3/16 inch and the other was a bit thicker than 5/16 inch.
Thank you for the advice Fox! Want to have a sleep over and help me sandblast the doors and cab? HR Lincoln, I have two pair of vice grips that make similar flanges. Its just VERY slow. I could argue that Apache1. I prefer 75/25 with solid core wire. I save the pure argon for TIG.
