It could just be that your tungsten and or tip geometry is not correct for a certain amperage range. Just because you have a good stable arc at 180A with (for example) a 1/8" tungsten with a short taper and a flat at the tip doesn't mean that it will be able to establish the same exact arc sta...

The only time I have issues when adding filler like that is when I am in fact welding too low, or using too big of a filler rod for the size of the puddle/amperage. What thicknesses are you having issues with? You really shouldn't be welding the same pieces at 80 if you can weld them successfully a...

if puddle is moving to one side check your torch angle. If you change angle it will push puddle to one side of other. Just light up on a piece and don't advance the puddle just change angle of torch you will see puddle flow it. Hard to offer suggestions with what we heard so far or seen. If arc is ...

I'm removing all scaling and surface contamination down to shiny metal. I've used several different types of abrasives to make sure I'm not contaminating the metal. This is happening on different mild steels from completely unrelated projects. I though it was the coming from the rod myself but the w...

I'm having a pretty frustrating relationship with my Lincoln Precision Tig 225. When welding mild steel my puddle does some very odd things. The puddle gets what I would call a red eye or dot that jumps around the puddle. It's hard to tell but it looks like it may be caused by an off shoot arc from ...
