Found my problem Zoama....I hooked my steel whip up and pulled the trigger...almost blew my wig off....TONS a argon flo...Hooked the spool gun back up an heard the wind coming from euro connector....The barbed connector from the gas line had burnt(as in melted..lol) from the main stub on the euro...gta bare wire in there too........From the Get go it wasnt shielding...once i went WFO on the argon..it welded sweet for 4 beads...My nozzle is the same...I pulled the ring forward..and the diffuser body blocked the rest of the suction issue as I saw it.....This bites...My machine is rock solid....My gun ???All I needs the barb fitting and forward to fix my deal.....Mark...Got some spare spool gun parts???lol
