10' 15 Series (150A at 25% duty-cycle) MIG welding gun. Uses HTP America® 15 Series consumables (the traditional 15 Series gas diffuser is not compatible with this gun; for the gas diffuser used with this gun, please visit the following link: Female Gas Diffuser f/81295B MIG Welding Gun). Fits many small (and typically Italian-made) MIG welders. Features a gas valve in the brass block at the base of the swan neck, located within the handle, since the machines do not include a built-in solenoid valve. The ring terminal connects to a stud on the inside of the machine, the two female spade terminal trigger wires connect to the trigger terminal on the inside of the machine, and the gas hose runs through the machine and to the adapter on the backside of the machine.
Excellent replacement for my MatCo gun
The equipment worked very well. I did have to make an adjustment to ensure that the main liner was gripped effectively in the drive system. After that adjustment (addition of a sleeve to better clamp the liner before the feed rollers), the unit works exceptionally well and is much better than the original unit that it replaces.
Works great Will order from you if needed in the future
Great Replacement/Upgrade Parts
I needed to replace the gun/wire tube on a low-end HF welder, and this item fit and works perfectly.
Took a little work to make it compatible
My brother bought one to replace the gun on his Clarke 100e Mk2. He was was having trouble figuring out the wiring since the original gun had only one trigger wire (small wire) coming out from the end that goes into the machine. He asked me to look at it for him. I'm not sure if all of the 100e welders did this, but his used the thick wire that electrified the mig wire as the hot wire for the trigger switch. So to wire it correctly, I wired one of the new trigger wires to where the original single wire went and the other one the the eyelet of the thick black wire. We tested it and the welder works like a new machine. I hope this helps if someone else has this problem since it didn't come with any directions.
I thought my old welder was about done with, but this new gun made it work like new again! I don't typically screw around with reviews, but I'm very happy with this.
