hi all. had me used pro 90 a while now and its been chugging along nicely.
i,ve only used it on little bits n bobs, but the other day i used it for a 2inch long continuous weld and when i tried to continue on the other bit it just seems to spatter and be very week 'no penetration'?. i've since tried practicing for about 5 mins or so, and as i use it more this happens every time..the first few welds are great then it just gradually gets weeker and leaves chicken poo...the following may be helpfull....i use 0.8mm wire 'steel'-setting 2 max, cos all lower settins just leave poo 'weak'- co2 desposables.
i've tried differant regulator settings for the gas no differance, however i used argon,co2 mix when i first got it and didnt notice these symptoms? could it be co2 gas causing this or could it be something more serious. it has never tripped the thermal cutout on me yet! anyway i appreciate any input given many thanks steve.
