Bought a MM 200 and the GA- 20C gun is beat up. The nozzle and the defuser and insulator need replacing. Profax has defuser, nozzle and tips. The insulator is harder to get. The Profax catalog list the thread sizes for these parts.
Put a miller Roughneck gun on the MM200, the Miller defused is 1/4" NPT thread. Thought how hard can it be to convert the GA-20C to accept miller Rough neck parts.
The GA-20C has 7/16-14 female thread.
Got a 3/8" barb x 1/4" NPT fitting( Milton). On the 3/8" barb side ran a 7/16-14 die to make threads. Then cut fitting to length.
Now can attach Miller Roughneck parts.
Bernard center fire parts are 1/4" NPT and Miller M25 are 1/4" NPT . Some of the Tregaskiss are 1/4" NPT.
