Change liner MIG torch aluminum

[@tombaker2523]

Thank you for this video now I know why my mig gun came with the plastic sleeve sticking out past the connection end it's for aluminum, my manual is very generic.

Most tfl liners do not have a copper or brass terminal on the burner side. Is it really necessary?

if i put the liner teflon for alu can i weld steel later with liner teflon inside the torch or i have to change it again? thanks
