Wireless TIG welder foot pedal?

Has anybody ever heard of or created a cordless foot pedal (remote) for tig welding? I hate having to buy new foot pedals for our Miller Synchrowave TIG/ Stick when the power cable gets cut or burned through. Thought about "bluetooth" signal.

As everyone knows, Miller makes one and to address concerns about it not being a good idea, I can honestly say that it works perfect. I know because my company has them everywhere. It's using the same idea that I mentioned years ago. Oh well...

I am working on a wireless prototype I'm developing for my Miller dynasty 300DX. So far, it works great. I haven't welded at anything above 200 amps (W/O high frequency) using it yet. I'm testing it in stages. I still have a couple of different modulation schemes to try before I will be satisfied. There is instant response & complete authority. I really can't tell the difference between my design and the wired version. I was mainly doing this for myself but might consider offering a conversion kit if there was enough interest.

How'd you go getting one??? I haven't cut mine yet but i'm about to take a axe to it myself!!! I'm sick of having to drag the lead along with the control every time i move position...welding the race car chassis on the jig means you have to move around a lot and i hate the tourchs with the control on them.
looks like you didn't have any problems with interference like the other replys say you will. I don't think the manufactures would allow something like that out for a welding shop to try.

Found one. Had in my shop for awhile, My guys loved it.<br />It was a demo unit and I (under protest) had to return it. Put in myorder for the first one off the assembly line. Still waiting. While inmy shop for a couple of months had no problems. Now every one of mywelders want one. I purchased mine for $550. from Freedom Special Tech.Springfield, IL. Product line sold off to new company. New contactinformation is:<div> <em> <b> <span style="font-size: 10.0pt;">Mike Long</span></b></em></div><div> <em> <span style="font-size: 8.0pt;">Vice President of Development /Open Wheel Specialist</span></em></div><div> <span style="font-size: 10.0pt;">Speedway Motors, Inc.</span></div><div> <span style="font-size: 10.0pt;">340 Victory Lane</span></div><div> <span style="font-size: 10.0pt;">Lincoln</span> <span style="font-size: 10.0pt;">, NE 68521</span></div><div> <span style="font-size: 10.0pt;">(800) 979-0122 ext. 3219</span></div><div> <span style="font-size: 10.0pt;">Direct (402) 323-3219</span></div><br />Mike has been very helpful in keeping me informed, but I too am still waiting.

Found out that Miller Electric RD is already looking into something like this.
Bad idea ! The RF around a TIG process is terrible ! What I'd do is change the wire to one that you can replace easily - mine has four cores, one for the switch, one for ground, one for 5V and one for the pot signal. Why not find an off the shelf audio cable - two phono leads or something like that. Mod the welder to use the RCA leads and then have a nice bag of cheap cables to swap when someone burns the wire.
It's possible to make one, but one of the reasons it's not wireless already is that it would become much more expensive to replace. Another reason is lag, a good welder needs nearly instantaneous response and wireless doesn't always offer that. Besides all that, your TIG also is likely to interfere pretty strongly with nearby wifi, bluetooth or other RF devices... so you might need some pretty sophisticated equipment to make it function well. Anyway, it's worth experimenting with. First thing I'd check out is what consumer devices will still operate well within arms reach of the machine while you work. Try a wifi gadget, a bluetooth gadget, a cordless phone, etc. It's best if you can monitor and test the signal quality and strength, but obviously you don't want to bring your most expensive electronics too close to your welding... so be cautious and avoid using your best gear whenever you have a choice. Of course, the best way is to change the scenario. First off, you should be able to replace a cut or damaged cord rather than buying a whole new pedal. In the future, come up with a way to protect the cord from sparks and falling debris. I suggest making a V-shaped channel to cover the cord along the floor/ground. Think of it as a welding mask for the equipment.
