hi rick, i have switched to argon, it was delivered and as i said i don't use it that often but i have welded the engine lid frame together over this week and the end of last week. i have left the gas lens on along with the pyrex cup, the gas is set at 10cfm, inside a building so no strong winds and very little if any breeze. i still have arc wander but nowhere near it was before. i do have gas flow pre, during, and post. i still have the dryer in the feed line and plan on removing that this week after getting some more feed pipe. i can start with a sharpened tungsten with a shallow point not a long tapered point, after a few minutes i get a small point appear at the end and not long after that i will get some arc wander.

having said all that the amperage is very low, i do sharpen the tungsten along its length not in circular pattern around the rod.
