hey im newly registered on here but have been looking for a while. i have been welding a fair while mainly mig but i do the odd bit of tig here and there mainly on mild steel, recently been getting used to using pulse so i can make a couple of manifolds for my evo and a friends evo, but cant seem to get it to how it should look its not me as i used a friends welder who makes manifolds for a living and with his welder it looked just as nice as his perfect penetration etc so we have put i down to the machine i have another tig welder a Migatronic PI serien 200 that is very rearly used so im going to have a play with that does anybody know any settings that would be a good start point im on pure argon ,#8 gas lense, 1.6mm 2% THORIATED RED tungsten using 304 sch 40 tubing and 316 1.6mm filler rods
