Welding body panels without warping
Anyone who has restored a classic car knows the problem: the MIG welder leaves hard, brittle seams that are difficult to work, and the heat warps thin panels. The Dillon torch solves both — and opens the door to classic lead loading as well.
Soft seams you can actually work
A gas-welded Dillon seam is soft and malleable. You can hammer, file and planish it exactly like the original panel — crucial when the surface needs to be mirror-flat under the paint. MIG's hard weld metal demands grinding, and grinding thins the panel; a Dillon seam you work with a hammer and dolly.
Minimal heat spread — the panel doesn't warp
Dillon's patented mixing chamber runs at just 0.5 bar, giving a concentrated flame with a very narrow heat-affected zone. The heat goes where you point it, not out into the panel. The result: straight, stress-free seams even in 0.8 mm sheet.
Lead loading — the original method
Before body filler, there was lead. Lead loading remains superior for quality restoration: it doesn't rust from within, it doesn't let go, and it moves with the panel. The Pro kit's Acetylene/Air nozzle gives you the soft, low heat that lead work requires.
Recommended equipment for bodywork
- Dillon Pro Kit — 8 nozzles including intermediate sizes for exact heat per panel thickness, the Acetylene/Air nozzle for lead loading, and extensions that reach inside sills and wheel arches.
- Welding rod H44 1.5 mm — thin steel rod that gives soft, workable seams in body panels.
- Nozzle 0.5 — the sweet spot for car panels if you're running the Standard Kit.
- Hose set and flashback arrestors for a safe installation.
