Welding Overhead 4F position tube to plate with 5/32" 7018 is a bit more challenging than with smaller electrodes but the same fundamentals apply for the most part.
Tight arc length, rod angle, and restarts are demonstrated with instructive arc shots and body positioning.
A look at a quick welding job on a tractor rim. This entire job took about 3 hours. Process used: MIG STICK | Materials used: Carbon Steel, 7018
In this video...overhead welding at 130 amps with 7018 1/8" electrode.
One mistake I made in welding school was running too cold on overhead
In this video, I am stick welding with 3/16" 7024 rods on a multi pass weld on one inch thick carbon steel. Also show some welding with other commonly used stick electrodes
