Im looking for a bit of guidance please. In the middle of building a flood sump pump system!
Ive done lots of tube welding both steel and stainless, but never really purged properly.
Ive assumed, maby incorrectly that you stick a bung in the pipe both ends, one end with the gas. Clearly i can lash this up with masking tape, but what are people using to bung the pipes properly. My google fu is not strong!
Also, ill be welding 316L this time. Whats the recommended tungsten on this? Ive got the red ones. Ive got plenty of 316 rod.
Pointers appreciated
