How do i hook up a smiley plasma/tig to an argon source? The regulator / gas hose is 5/8-18 (CGA-032) and smiley is a barb. I don't want to cut the gas hose because i got a mig that takes 5/8-18 and can't seem to find any adapters.

 

Buy another hose?

 

Any local welding supply will have the inverted flare to barb adapter on the shelf. I broke mine once. The welding store just gave it to me.
