    Re: FS: Lincoln High Freq Unit

    Hi, I have a Lincoln G9 Pro that I would like to add ac tig capability to. Reading thru the manuals, it sounds like this would work, but it looks like I might need a couple more bits to make it work - the G9 Pro manual mentions a HF bypass capacitor that ships with the kit, but gets installed in the welder, and the Hi-Freq manual I found mentions a required Arc Start Switch, shipped with the unit as well, which plugs into the Hi-Freq. Is this part of the torch? Also, what kind of torch is it? Is it water cooled? And do you have any photos of the torch?

    Thanks,
    Eli

    This may be the dumbest question for the day but I gotta know.

    Will this work with a DC machine? I thought HF was only for AC and to keep the arc lit during the zero crossing. In my mind, the dc would wash out the HF.

    Insane, yes it will work on DC. On DC you set the switch to "start only". When you hit the pedal the HF comes on to start the arc so you don't have to use scratch start to get the arc started. Other than that it won't help at all.

    These units work great. I sold mine with my Ranger 9 in trade for my PrecisionTig 275.
    I kinda wish I would have kept it in the deal now.
    If someone needs this and doesn't buy it, is missing out!!

    Can this unit be hooked to any AC welding source?

    Yeah, you won't have amperage control tho.

    Not the greatest setup, but it works.

    PM Sent. I have been looking for one of these for quite some time to complete my welding rig. I have a invertec V350 and LN-25 that this would go nicely with.

    Unit arrived on Friday,it was wrapped to the nines in bubblewrap and packing paper. Everything was as Josh stated. Now I just need to make a cable to connect the power and get another set of guages and hose for the gas and I will be in business.
