Not familiar with the machine but was the polarity on DCEN? If your on DCEP it will fry the electrode. Looks like you can put it on stick mode, select the polarity with the leads, and I assume you would have to use a torch with a gas valve.MinnesotaDave, possibly. When I was newer to welding I remember trying that on accident with a Miller machine. It just kept trying to melt the tungsten to the workpiece though so I haven't done that since. That is how I found out that you can use a TIG wand as a stick electrode holder though.
I used a stick machine with a similar setup for a while, and would never go back to it unless I need to for some reason. I would follow the advise above and just use caution
