Can I use a TIG welder to melt metal in small crucibles?

The subject says it all. I wonder if I can use a tig torch to melt metal in little (or not so little) crucibles. With at least 5kW at the arc, I could melt pretty big stuff. First of all, I don't have a clue... Secondly, would it be possible or better to use the stick setting and 2 carbons to melt the metal? |

Possibly. The nice aspect of tig is flow of argon, protecting the metal being melted. I am fully open minded here. i This would almost be worth it's own setup. I have the stick welder, now how much would I need for an argon regulator and bottle plus some spare tubing? How much carbon contamination could one expect, I wonder? -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |

how much would I need for an argon regulator and bottle plus some spare tubing? I think you may be slightly confused. A stick welder has no facilities for putting the argon in the same place as the electrode. The best you could do would be to spray out the argon somewhere near the electrode. Does anyone know if argon is a heavier than air gas? I'm guessing it is, but it may not be much heavier, and thus difficult to completely cover a crucible. |
