Are you sure about 3/16 tungsten? if so try 1/16. Be sure aluminum is spotless clean. Wipe with acetone, after sanding. Are you inside with no fans or air blowing? You are using argon 100%? Try some 1/16 filler.

More info as far as metal thickness would help. But, what I've learned about welding alum is to apply more heat off the get go and back off if needed. If you ease into it a lot of times it'll fold away like your talking about. 1/16" is small tunsten unless your welding thin gauge alum. , you'll be going through it quickly.

Thought op said 1/16 aluminum

For a Diversion 180 you should be sharpening your tungsten, not balling it. And surely you mean 3/32 dia.

Have you already developed proficiency in welding mild steel coupons?

Lot to learn.

Starting with aluminum may well slow the developmental process.

3/16" tungsten won't fit in any torch that comes with the Diversion.

Aluminum likes to be welded hot and fast.
