That's what i thought, i'd have a hot gun, which for the price i can live with.
The gun plug is a 2 pin flat,control power is provided from the feeder unit.

Maybe this afternoon i can plug the Bobcat up and give it a try. Want to get this deal going so i can get the power sorce out of the way.Darn payin work is messin with my playin work again.

Good news, we have a 250 amp portable mig!!!! Smooth as glass too, the hot gun i can live with.
The bad news is i had to order a gas valve for it, got tired of messing around trying to get the old one function with some reliability, $78.00. Also ended up robbing the contactor from the old power sorce and plugging it in. It aparently completes the 110v circuit that gets power to the valve,but there was space in the control box for it so no big deal.
Now some .045 wire,liner and tips, scrap out the old machine and i'm done.

Great...

sounds like you are on your way...

you might consider keeping a spare solenoid valve on hand just in case..

I have bought several of them brand new over the years in the $5-15 range...

do a fleabay search for "asco red hat solenoid valve"

you might surprised at what you find...

Excellent.

While your out and about scrounging, you might want to try and find the
special contactor that the suitcase feeders use to switch the welding
current.

what you can do is install 110v relay coil across the gas solenoid, then use one of the normally open contacts to control the power source, so it wont be a hot gun.

Fraid it would take a Real contactor capable of handling 250 amps... either in the 10E or modding the Bobcat 250... either one doable.. but will take some work...
If I were to do it... I would add it to the 10E.. would be simpler and would leave the Bobcat unmolested...

easy enough to get used to a "hot gun"... so why worry about changing it...??
