PowCon 300 SS Welder Gloat

[Ulma Doctor]

i was surfin craigslist yesterday and found this little beauty...


it's a PowCon 300 SS Heavy Duty DC Inverter welder.
i snatched it up for the ridiculously low price of $300.
these are extremely tough building trades quality inverters that will take a pounding all day long at high load and won't quit on you. iv'e welded extensively with powcons when i was an iron worker apprentice. i have used these units on structural as well as deck work. i'm totally stoked and got it for a song!!!

Help me out here... What process does it support?

DC stick machine but can also do scratch Tig, carbon arc gouging and stud welding.
300 amps on 3 phase and 200 amps on single phase.

You can download the manual here

this unit can be used for stick welding up to 300 amps DC. at 300 amps it has a 60% duty cycle on three phase. when configured in the single phase mode it will weld 200 amps with a 60% duty cycle. it consumes 41 amps on single phase and 32 amps on 3 phase power.
other PowCon units can support, mig, tig, and stick from the same unit, but you most likely wont find them for $300...lol

i haven't gouged with one..
i'm gonna have to give it a shot thanks Don!!!

Does it have both Constant Voltage (cv mig or flux core) and Constant Current (stick)?

 

[Ulma Doctor]

this unit is constant current.
other versions have a switch that you twist to change between processes.

 

[sniggler]

Can you switch polarity on that unit?

 

[Ulma Doctor]

i guess i should have posted a picture of the front of the unit.

yes, you just switch positive and negative leads.
it has female terminals, common twist lock welding(tweeco) connections in the rear panel.
they run equally well DC+ or DC-
they aren't indestructible, but darn near.

Looks like a nice unit, I've never used one but it should do the job.

thank you Paul,
they are fantastic units and a real pleasure to work with.
they have ability to control the current from a remote switch, you plug into the back of the unit.
saves a lot of time running back and forth to the unit. if your heat isn't right turn the remote dial,
baddabing!!! corrections are instantaneous.
it's really a great feature if you got 150ft of cable out.
