Welding???

[Dorset Lad]

It all depends what materials you are wanting to "join". Gas is fine for welding or braizing mild steel, or silver soldering non ferris metals such as copper or brass. The working temperature of finished job is also a considderation. For metals such as aluminium or stainless steel then TIG is the best option. you can use MIG for alli and stainless but you need different gas mixes than for mild steel. Gas welding is also only suitable for relatively thin materials. Thicker stuff needs to be electrically welded. Arc (stick) welding is probably the best general purpose method and can be done using a portable generator or welding generator directly driven by a small engine. Some mobile workshops have one driven off a PTO.
