MIG Foot Pedal Idea?

admin

I run a business where I make a lot of metal furniture and sculptures so I'm constantly working with a variety of thicknesses. Last night, I was discussing how annoying it is to have to constantly change the feed speed when I'm tacking together a project that has multiple different gauges when I had an idea. Why couldn't I make a foot pedal to control the speed?! I did a little research to see if anything is currently being marketed that can do this but found nothing. The idea would be similar to a volume control pedal or crybaby/wah pedal for guitars. I can adjust the potentiometer with a board at my feet and even remove my foot without losing or gaining wire speed. I'm honestly thinking that I could just tap in on the wires that are existent in the welder for the potentiometer that controls the wire feed and put a female plug on my welder so I could even unplug the foot pedal. My questions are pretty simple: Am I just crazy and they do actually make this? Does this sound like a plausible idea to anyone else? Do any of you know someone who has tried this or tried it yourself? Now I doubt this one but would there be any inherent danger in doing such a thing?
Reply:Never seen it tried but I think you will want to be able to adjust power and wire speed.GravelThe difference between theory and practice is that in theory there is no difference.

Reply:I had messed around with a foot pedal while stick welding opening root butt joints in welding school it actually worked pretty well   I don't see why it wouldn't work for mig
Reply:This would be sweet on Miller 350p where adjusting wire speed automatically adjusts all other parameters concurrently. You could pulse on pulse, work long fillets on Aluminum, and fill craters. Dear Miller, ...Constant Current Weldor.

Reply:I have xmt 304 auto link. Its on a 1phase 50 amp breaker . On the cart is Xmt 304 cc/cv power source. S/D 70 with Optima™ MIG (GMAW) Pulse Control. With this setup if you press the stinger drive button with special sequin amount of pulls . There is A couple of preset volt.amp drive speed standerds. Yet withOptima™ MIG (GMAW) Pulse ControlYou can control everything. Pertect with this unit. You can add a gas mixer. And can weld like a pro. Perfect for what you wanyBlackfire Opp
Reply:Seems like the Miller units with the infinite controls could be configured for a foot pedal.  Not so much the MIG units with tap settings (unless speed only).  Would it be of any value to have a switch to choose whether the pedal controls voltage or speed?GlenMiller Dynasty 200DX - Millermatic 350P - Hypertherm Powermax 45Want to sell!! - Hobart Handler 150
Reply:The way my production unit works is this .1. what material. Alum. Steel ect2. thickness3.wire diameter and type4. Volts5.pre and post flows6. SpeedWhen that is dialed into my mig GMAW it is a preset in the memory. My trigger on my gun has a sequence for changing preset depending on material. So you do not have to go to the machine. My Optima™ MIG (GMAW) Pulse ControlDoes the same thing but on a 30ft tether to machine. So again you don't have to touch the machine.
