WebApr 29, 2024 · There is a relationship between arc voltage and arc length. A short arc decreases voltage and yields a narrow, ropey bead. A longer arc (more voltage) produces a flatter, wider bead. Too much arc length produces a very flat bead and the possibility of undercut. 4. Set the wire feed speed. Wire speed controls amperage as well as the … WebJul 24, 2024 · Welding transfer mode. It may be short-circuit, spray-arc, pulsed-arc, or globular transfer. Each mode pairs better with certain shielding gases. For example, you should never use 100 percent argon with a spray transfer mode.
