WebAug 15, 2010 · Thanks Les, if it eats up Argon, that would be to costly for sure. I was thinking mostly to use it with O1, so it would be a quick trip to the oil tank, but if it takes alot of flow to keep the oven purged, it would be a waste of time. But in case I want to try it, what did you use to pipe in to the oven, I was thinking stainless steel tubing. WebWeld purging is a critical component to ensuring a quality weld, especially when working with stainless steel. Weld purging is a process where oxygen is evacuated from a pipe, tank, or chamber using a noble gas such as argon or nitrogen. This process prevents oxygen from entering the weld pool, which can cause poor quality […]
