View Full Version : high frequency unit
08-22-2004, 12:47 PM
i have a miller trailblazer 250g and i am looking for a high frequency box to add to this machine so that i can weld aluminum alloys. does anyone know of a welding supplier that i can contact to get a price quote on this product. i have priced one in my local area and i just want to shop around and see if i can find anything a little cheaper. i have heard of people picking up high frequency boxes much cheaper than the price that i had gotten so im wondering if anyone may know anything about the cost of this product. THANKS.
Try Brwelder.com, they are in Maryland.
Have a great day.
Look on ebay, check the big internet welding suppliers- but unless you find used, you probably wont save all that much.
I have a miller HF unit, which I just ordered from my local welding supply and paid what they asked for it- I needed it right then, and I find my local guys treat me right- they usually discount a little for me, but I have an account, and spend an average of $300 a month there on supplies, so I often get freebies thrown in, or delivery on urgent parts, just plain good service.
I have used the HF unit with the trailblazer, and it works great. We do a lot of site tig welding, mostly stainless, so I am usually running it DC, start only, but it will do AC continuous very well too.
I have a little cart made up with the HF unit, a Radiator, a water cooled torch and foot pedal, and I can either run it in the shop with an inverter power supply, or throw the whole thing in the truck and run it off the trailblazer.
I would recommend sticking with the miller unit just for the plug and play aspect- everything plugs right in, and it is real easy to move it around, or reconfigure it- foot pedal, remote hand controller, scratch start, move it from power supply to power supply, and plus it has a gas solenoid, which not all of them do.
My only gripe would be no adjustable pre and post flow.

Ries...thanks for the info. i thought maybe a HF unit would be a little cheaper than the price i got from miller but so far, it seems like thats the going rate so im gonna have to just do like u did and pay the price for one as i need it anyhow. the local welding supply around my area wants $800 for one.
im also interested in that little water cooler that u mentioned. i have a water cooled torch and a foot pedal so all im lacking is the water cooler. i know the little bernard coolers are pretty expensive so i was wondering approx. how much u have invested in ur little set up. i was also wondering how i could make one and after reading about urs, i see that it does sound like it works pretty well. if u can give me a little bit more info on how to build one and the approx. cost i would appreciate that very much too.
also thanks again for the reply.
