Does it work for TIG in original as-designed configuration (DCEN)??? As in welding basic mild-steel 1st?

Yup, have to reverse polarity for aluminium DC TIG welding DCEP. Have dedicated tungsten for it as well because it balls up tip. Also should use helium for shielding gas instead of argon for better penetration because alloy wicks heat away from weld-zone extremely fast compared to steel. You should learn to scratch-start TIG anyway and not depend on HF button.

Should only be TWO cables to reverse. The actual power+ground ones.

The gun trigger-button is 3rd wire that should still go to relay/power-transistor to turn it on. Which really should only activate gas-valve and HF. Nothing to do with power. Sounds like you reversed wrong leads and disconnected trigger-button and swapped it with ground?

1. Post some photos of wiring-connections on original TIG configuration that works for steel.
2. post photos of your reversed polarity connections.

BTW - Harbour Freight has decent TIG/stick welders for $149.

EDIT - is this unit you got? https://www.amazon.com/dp/B08CDQJR6W.
No way you're gonna get 200a out of 110v supply... how are you going to get 45a 110v input line???
Output appears to be: 10.6v/15a up to 18v/200a in TIG mode.
