Dillon vs ordinary oxyacetylene — what sets them apart
Both are gas welding with oxygen and acetylene. But that's where the similarity ends. Dillon runs 0.5 bar on both gases, ordinary oxyacetylene runs higher pressure. The difference is enormous: softer flame, better control, soft seams you can work, and cheaper operation.
What ordinary high-pressure gas welding gets wrong
Conventional oxyacetylene runs higher pressure and produces a turbulent flame that scatters heat in all directions. Thin sheet deforms, sensitive materials burn through, and the joint becomes hard and brittle. Precision work becomes a challenge.
Dillon's 0.5 bar flame — why it works better
Dillon's unique mixing chamber blends oxygen and acetylene at exactly the same low pressure — 0.5 bar. The gases flow laminarly, the flame stays soft and concentrated, and the heat stays where you point. The result: precision, control, and soft seams you can work.
Concrete comparison: Dillon vs ordinary gas welding
| Dillon | Ordinary gas welding | Advantage |
|---|---|---|
| 0.5 bar on both gases | Higher pressure, varying depending on tip | Dillon |
| Soft, concentrated flame without turbulence | Turbulent flame that scatters heat | Dillon |
| Soft, workable seams | Hard, brittle seams | Dillon |
| Sheet doesn't warp, stress-free joint | Risk of deformation in thin sheet | Dillon |
| Cheaper operation, longer bottle life | Higher gas consumption | Dillon |
| Runs without electricity, fully portable | Runs without electricity, fully portable | Equal |
When Dillon beats ordinary gas welding
Thin sheet
Weld 0.8–1 mm sheet without deformation or burn-through.
Workable seams
Hammer, file and planish the joint — impossible with ordinary gas welding.
Sensitive materials
Aluminium and cast iron demand soft controlled heat — Dillon delivers.
