Pro tip: a chat with a pipefitter changed how I set up my welding leads
I was grabbing coffee before a job at the plant in Gary and got talking to a pipefitter named Ray. He saw my leads all coiled up neat on my cart and said, 'You know, a straight run from your machine to the point of work gives you a cleaner arc, less heat in the cable.' I tried it that day on a 2-inch carbon steel line, just laying the lead out flat for about 50 feet. The arc was way more stable and I didn't have to crank my heat as high. Anyone else run their leads straight instead of coiled up?

That sounds like a shop floor myth to me. Coiling your leads is just good cable management and keeps your work area safe from trip hazards. A straight run across 50 feet of plant floor is asking for someone to get hurt or for the cable to get damaged. The difference in arc quality has to be minimal compared to the real risk of creating a mess.

But coiled cables can act like an inductor, messing with the current flow. That can cause a weak or sputtering arc, which is a real problem for a clean weld. Sometimes the neatest setup isn't the best for the actual work.

The Lincoln tech manual from 2008 specifically warns about inductance from coiled cables on page 47. It's not a myth, it's basic electrical science.
