Astro_Al Posted October 26, 2007 Share Posted October 26, 2007 Not sure there are enough tiggers on the forum to support tig questions(?) but thought I'd ask anyway. Anybody ever DC tigged ali - I thought it wasn't possible until I saw this: http://cgi.ebay.co.uk/Rods-for-DC-Tig-Weld...1QQcmdZViewItem I'm not gonna buy them as I have a tig with AC function now, just wondering if anyone has used these? Cheers, Al. Quote Link to comment Share on other sites More sharing options...
T1G UP Posted October 26, 2007 Share Posted October 26, 2007 To my understanding of the welding process of ali AC is used to 1 heat the material so it melts and to then 2. burn through the "skin or oxidisation"of the weld pool to actually allow you to weld it.Hence the square wave and the frequency adjustments required. I can't see how the rod would make a difference but i'd like to know more myself. Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted October 26, 2007 Author Share Posted October 26, 2007 Exactly. It says it has a flux in the rod - is that gonna make it like arc welding? I wonder if it leaves a slag on the tig weld - now that is odd! I'm kinda tempted just to do it as an experiment. (But I'd rather leave it to someone who knows what they're doing!!!). Curious... Al.

T1G UP Posted October 26, 2007 Share Posted October 26, 2007 The only thing that the flux could do is prevent the skin or the oxidisation from forming.then the dc would just melt the ali.Worth a try. Take a look on the eutetics(sp?) site Quote Link to comment Share on other sites More sharing options...
