Thread: "Hi Freq"

I was given a Lincoln 250 amp 110V "Hi Freq" box and I would like to use it with my Lincoln AC/DC 225 amp 220V welder.Will they work together.If so how do I hook them together?Do I need to run my gas through the box?The box has a remote switch that attaches to the torch and I don't have a pedal. I am assuming that my voltage will be controlled through the machine and does it matter if the box is 110 and the welder 220.Thanks,Ron

All the manuals are free online. scroll down to high freq in the window, then look for your model number.

It does not matter that the high freq is 110. Just plug it into the wall.
You just plug the electrode and work leads into the high freq, and then you need a pair of shortie leads to connect the high freq to the welder.
It will work fine with a remote switch, a pedal, or just by setting the amps on the welder itself.
Depends on the box, but most will turn your argon on and off with the arc, so, yes, you want to plumb the argon thru the high freq box if it has a solenoid to turn the gas on and off. Its a lot more convenient- if it turns off the argon when you stop welding- as it never forgets and lets the whole tank run dry.
Some will also turn off and on coolant water. Most of the time, though, if you are using a water cooled torch, you just let the coolant pump run all the time.

Thanks Ries, that's exactly what I have been looking, for my searches fell short!Ron
