Can a PowCon 300sm Tig weld if it has a plugged in pedal?

go to see Welding Machine for Can a PowCon 300sm Tig weld if it has a plugged in pedal?

I'm looking at a PowCon 300sm to buy and noticed it has a PowCon pedal plugged into a factory port. I know the "sm" stands for Stick and Mig but can you Tig weld SS and mild steel with this machine? I know it can't Tig aluminum without a HF box.thanks in advance for any replies!Mike
Reply:There's no gas control solenoid on those, so you'd have to run a torch valve, also no cap discharge start so you'd have to scratch start. But the pedal should control your current. Have to check the pinout and machine pin out, but I'm about 95% sure Sent from my SAMSUNG-SM-G870A using TapatalkPowcon 300st (my favorite)Miller Goldstar 600ssLincoln Idealarc 400/400Miller 12vs2 LN25'sMiller Deltaweld 302Miller Bobcat 250 G EFIMiller Bobcat 225d Plus (Dropped a valve, up soon)Everlast 255ext (ordering soon!)

I've worked with their technicians on Sundays before. They are very dedicated people.Sent from my SAMSUNG-SM-G870A using TapatalkPowcon 300st (my favorite)Miller Goldstar 600ssLincoln Idealarc 400/400Miller 12vs2 LN25'sMiller Deltaweld 302Miller Bobcat 250 G EFIMiller Bobcat 225d Plus (Dropped a valve, up soon)Everlast 255ext (ordering soon!)
Reply:They have rave reviews but I've never heard of them before. Been working around metal fab for 30 years and don't remember seeing any lol. We had a couple xmt's in a tool shop I managed and they were really handy machines. They'd Tig like a dream.Do you know if you can plug and play a spool gun on the 300sm?thanks,Mike

Reply:Not sure about that. I don't know much about spool guns. If they run off of the welding current and just have a remote switch, as long as you have the right 14 pin setup for remote contact, I don't see why they wouldn't push al wire.Sent from my SAMSUNG-SM-G870A using TapatalkPowcon 300st (my favorite)Miller Goldstar 600ssLincoln Idealarc 400/400Miller 12vs2 LN25'sMiller Deltaweld 302Miller Bobcat 250 G EFIMiller Bobcat 225d Plus (Dropped a valve, up soon)Everlast 255ext (ordering soon!)
Reply:You generally can't TIG aluminum with a DC welder. You need AC and HF continuous.  (For the average welder weldor)  Before some wise guy gets on here. Yes you can do DC with helium but it's a specialized process and primarily for thick aluminum.Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:Scratch start works fine on SS and carbon steel. Never had a lift start until I bought my XMT.  As far as using a pedal I have never used one. I don't see a need for one welding DC tig. There are threads in the powcon section about adapter cables for feeders. Dan D.Last edited by DanD78; 01-26-2016 at 09:55 PM.Manipulator Of Metal
