question for welders

[Dragsinger]

thinking back the comment about oily/dirty may be my trouble. The tube that gave me trouble was oily and I only did a quick wipe. I will clean and retry.

Remember, anything you do not remove from the work or the filler will be in your finished product.

Larry,
This has bitten me more than once. Clean metal, and filler is a big deal. TIG seems to be even more critical than MIG, or maybe I just don't have the experience with TIG that I need.
Keep pushing buddy!

Cleaning the weld area is definatly the first place I'd suspect, But as was posted earlier, I've had voltage issues from time to time as I'm at the end of a long run from the high voltage transformer.
Try having a helper moniter the line voltage while running a weld bead, sometimes the volt drop is not evident until the welder is under load.
Also once had a similar problem that resulted from a faulty ground cable that was broken at a factory splice in the cable and was under the insulation and was not visable, Altho I don't suspect you would have that problem with both welders.
