Most probably, the potentiometer is being used by the welder as a voltage divider rather than a variable resistor. The welder applies a voltage across the 10K resistor and the slider gives the welder a variable voltage depending on its position. The voltage ranges from low to high (or high to low) depending how it is configured as the pedal position is changed. Pots can be made in different ways. They can provide a linear output or the resistor can be manufactured to not be linear. Audio gear (probably like the one you purchased at the music store) usually have audio tapers which try to mimic how the ear responds to power in sound. Audio taper pots are Log 10 based which is how our ears sense sound. That explains why you see more or less response at the ends of the slider travel.

Instead of pressing pedal with toe turn it around and press with heel for more control. Your toes will bend easier while staying at low point while you press down with the heel and you can hold any position easier doing so. Try it without a pedal while sitting down lift heal while toes are on the ground and feel the motion, your still pressing with toes to raise heel but you can gauge how high or low and hold any position. Anyway try it backwards to see what I am talking about, there is no rule saying you must use the pedal the way everyone assumes you must.

Nice idea...will try. I am a stroke (brain) experienced engineer/welding hobbiest. My foot control is right foot only, but hand/torch can be either. My foot sucks. Most hand torch controls offer trouble, because they are on the torch. I am trying alternatives. Wire feed right hand with a middle finger (palm held) controller seems best for me. Can feed wire and control amps in comfort. Recently tried left control/right torch...not bad, but have WTF just happened issues. (uncontrollable flinches)

I have an SSC pedal on my Miller Synchrowave 250. Those pins at the hinge point are spring loaded and you simply push both sides in to take the top off. The top of the pedal doesn't actually attach to anything else. There is a small ever inside it bears against with a little extra travel to take up some slop. When you pop the top that lever will spring up maybe 1/4". No flying springs or screws. I like how stout your homebrew pedal is, good use of tubing.

This design is a very good way to avoid gears and sloppy mesh between them, very clever made! Also the releasing of the switch is brilliant. And the adjustable tension spring to move the pedal back up is a great feature. If you could get the workings of the pot string reversed, so the pedal provides tension instead of releasing, you could have a bit slop in the string to take up the movement used to release the switch. I think I will try to build a pedal that way, the SSC pedals are just too expensive for me, but I would love to see what's inside!

Great ideas here and I've only just watched this as I wait to buy my first tig to learn on. I love your production style. None the less, I've an electronic background and whilst building a helicopter simulator, I'd built rudder pedals of the sim similar to your pulley setup and was great until the pot's wiper picked up junk and ruined it mid-flight (no harm in a simulator of course but still annoyingly!) I'd imagine that in industrial setup this is a real hazard. Then I found Hall effect sensors! You seem familiar enough to electronics to make modifications etc to your tig so are likely already aware of these, but they work exactly like a pot but using magnetic fields (be aware: there are two types.. Schmit-type on/off - like in tachometers; and "normal" which magnetic field adjusts output) I could see that a Hall effect sensor installed on the baseplate of your footpedal, with a good neo magnet on the moving part will remove a lot of the complication in the mechanics of this design. As it has been said before "complicated things break reliably". Drive it with discrete components or feed it to an arduino that will manage your pot thresholds etc.. You'd need to get 5vc dc to it - but you could put the arduino in your tig base... *Shrug* (plenty of ways to skin a cat) Anyway, just thought I'd share an idea to see if it might help vs3 of your design - or maybe give someone else an idea to expand on.

That's what I get for watching your videos in reverse order. 😁 But seriously, I have an old (1970's) vintage Lincoln TIG-300/300 welder with a saturatable core transformer rather tham today's modern IGBT solid state units. It's new enough to use a 10K pot and a circuit board to control the core current but too old to find any documentation or even a used pedal designed for it. There must be some Google-foo cross talk between KZbin and Ebay, because my searches for info and used pedals led me to this video. Great info!

Love the videos, great job. Given you have three inches of pedal travel you could get rid of a lot of the pulleys for the round potentiometer and use a slide potentiometer attached to the pedal, this would then use the pedal spring as it's return spring. Also using a micro switch with lever and roller on an adjustable plate would give you better adjustment over the on/off switching.
@EVguru9 жыл бұрын
Hi Tony, The 'Pot' is wired as a potential divider. One end of the resistive element will be ground and the other side will be a supply voltage (5v, 10v, 12v, something like that). The voltage on the wiper contact varies with position. The value of the pot won't affect the voltage output and the next value up or down in the range will often wok just fine. If you wire a pot as a variable resistor and connect it across the ground and supply terminals, you can measure the voltage as you decrease the resistance. When the voltage starts to drop significantly, disconnect and measure the resistance. You can use a pot down to that resistance. A pot of too high a resistance might not give you full range, but won't do any harm. On my Chinese TIG, the pedal overrides the main panel current control, rather than the panel control becoming max current. To fix this, I have a second max current pot on the side of the pedal.

One small change would maybe help you a bit- there are potentiometers with built in switches on the same shaft that work from the zero position. I.E. the first part of the rotation closes a switch built into the pot body, but as the rotation continues, the resistance changes directly with the amount of rotation. The wiring for the pot is discreet and has 5 pins which you can combine or use independently. These are cheap and can be found at Mouser or similar electronic supply houses. Also, there are pots that are linear with the rotation or another type called "logrythmic" which comes on slower but builds faster at the far end of the rotation.

If the potentiometer is being used as a voltage divider (likely), then this would be an ideal application for Arduino technology. One could use any sort of peddle position measurement approaches, and program the Arduino to put out the desired voltage. The position to signal voltage to welder amps could all be perfectly mapped in a table in the software, thus allowing tweaking to perfection. Presuming that the welder emits a voltage on one of those pins, then that might be sufficient to power the entire peddle project.

By the way Tony that SSC pedal should be able to come apart if you press the pivot shaft in on both sides as it should be springloaded to be able to remove the rocking cover. Just press a screwdriver and they should pop in and once you release they should pop out into position again just like wrist watches bracelet springs. Show us the inner guts on that one as i would be interested on having a look inside. That is exactly the setup i need to make a pedal for my Kemppi unit

All you need is a normally open switch and a pot. Use the spring to hold the pedal on the switch so that when the pedal is pressed the button on the switch goes up and closes the circuit. Then all you have to worry about is putting the pot on the hinge. Oh and make sure if the pot you need is linear or logarithmic. Linear basically changes resistance by the same amount for each degree of rotation. Logarithmic doesn't. Also you could cut teeth on the edge of the pulley and use it to turn the pot.

Very cool Tony, I was just out in the shop running a few beads and making a 3rd hand out of re-bar and scrap steel...and TIG brazing some Copper onto the contact surfaces to increase conductivity. Brazing with electrical wire is fun, the puddle looks trippy and the Copper melts like Gold does, especially if you're not careful with the heat. It's pretty easy to control the heat with my footpedal now that I've gotten in my practice, but since the pedal defeats the amperage control, it does take a bit more brain power to keep in check. I was wondering if you knew how to add a dial to the foot pedal to control the top end? If not I was thinking about adding a bolt I can adjust to prevent the pedal from going too far, but reducing the pedal's range wouldn't be ideal, and I am sure you feel me on that. Aloha...Chuck.
@ThisOldTony8 жыл бұрын
Thanks Knolltop. Re: limiting the machine, all depends on the machine. Rather, all depends on the potentiometer setting. Usually 0 ohms = full machine current. If you add a 2nd pot in-line with your foot pedal you should be able to cap the current. Say your machine uses a 0-10k pot. That's your whole current range. If you add another potentiometer somewhere, so it adds to your footpedal, then you're bumping the 0 ohm setting away from zero (can't reach full amps). Say your second pot is also 0-10k. If you set that to 1k, then your foot pedal is now 1k-11k. So your machine can never reach top amps (0 ohm). If you set it to 5k then your foot pedal is 5k-15k. Make sense?
@KnolltopFarms8 жыл бұрын
Yes, that makes sense, and so I think I can figure out which wires run to the pot and where to install the 2nd one...just so you know, I've got an Everlast 160sth and I really enjoy it. The only thing missing is AC for Aluminum... Oddly enough even after years of working with sophisticated machines and all the control in the world, I have gotten used to not having amperage perimeter controls. But, I'm sure I'd spend less time on testing/practicing just where to hang my foot, depending on thickness, if I had a dial. Plus, welding is a little more fun for me when I don't have to concentrate on feathering so much, and can just bury the pedal... I'll let you know how it goes, and thanks again...Chuck.

Tony I didn't read all the replies but it seems like you could tune the pedal motion without worrying about the pot and switch timing and take care of that with gain and offset in an op amp circuit with an adjustable set point for the trigger. Did you ever measure the voltage across the two outside legs of that pot when it's plugged into the machine? I'm and assuming the welder give an actual not set point amp reading so you could measure the actual voltage off the center (wiper) that gives you 0 and full output. you could also mount the controls off the pedal if it's something you would want to tweak during use.

The pulley at the heel seems a bit over-complicated. You could probably have just welded a rod or plate to the heel of the pedal (at 90 degrees, pointing down), and attached a longer spring (or that same spring with the steel cable) directly to it. It would basically do the same job as the vertical part of the cable. For the switch (assuming that was originally one of those switches with rollers), you don't really need to worry about the throw matching the motion of the pedal if you mount it vertically and use a sliding cam (again, welded directly to the pedal) to press it. Not sure if there would have been enough space inside the pedal base to do that, tough.

i have a tig stick welder ( boc 185ACDC ) and i want to buy a slider for the torch, the manufacturer wont tell me or supply a diagram that would tell me the resistance of the pot so i can get the correct one, how do i find out which resistance value on to buy? cheers in advance

I built a foot controller I think after watching the first video. It is janky. Only used once, but with this video I'll be able to make adjustments to it and hopefully get it to work right

why don't tig torches have a trigger, like an RC car?
@ThisOldTony7 жыл бұрын
Google "Tig Amp Control" -- you might be surprised at just how many options there are out there. There probably is a trigger.

I really love my everlast 140A stick welder but adding a pedal for tig welding would be super.

Hi Tony. First of all I'd like to say thank you for your time and effort for your tip top editing skills. It makes watching your machining skills a little more enjoyable! (English sarcasim) Can I ask one question? Is that a Kemppi plug I saw on the video? if it was would you share the pin wiring with me please, as I have a kemppi mastertig 3000. ps loved the cnc welding also your new vortex tube. I didn't even knew they existed till you mentioned! Thanks :)

Thanks David! I'm afraid it's not Kemppi, it's a Cemont. Have you tried emailing Kemppi support?
@DavidMFabrication7 жыл бұрын
I'll give it a go. I'm guessing they will be very reluctant and if I make up an elaborate story about my R11F they will probably just say take it to a repair centre. It's worth a shot though. Thanks Tony.

I have the wiring diagram for a Kemppi C100F pedal if that's what you are looking for, 4 and 10 pole plugs.
@DavidMFabrication7 жыл бұрын
1873Winchester unfortunately it has to be a R11F according to Kemppi. The C110f doesn't work according to them. Thanks for the offer though.

1873Winchester Hi I would like text you about wiring diagram for Kemppi C100F. If you still have please text me.

TOT I am watching this because I got a Lincoln Tig 175 today,without a pedal. Thinking if I should make one or buy one.

Ernie Ball guitar company makes these pullys and springs for there volume and wah pedals sells them for $25 bux change the string to a metal cable and ur set good work but you can buy an EARNIE BALL MVP STRING SPRING AND BEEF IT UP SAME EXACT CONCEPT GOOD WORK

Very usefull. Been thinking about acellerator for electric go kart, the speed control uses a pot, the internet is awash with hall effect witchcraft.. keyboard volume pedal, top tip.
@vladmirputin71396 жыл бұрын
Any reason you didn't just use an arduino with a digipot and a hall effect/IR sensor?

I think the only thing your home made pedal needs is a nice slab of diamond plate on top. That is to say aside from a working switch...
@Romuls7533 жыл бұрын
If your machine sees 10k ohms for the minimum and the act of switching it on drops it to 9k why not install an 11k resistor so you get the minimum at start? Or why not use a normally open start switch that stops the machine when it's closed?

Very late suggestion. Engineer the switch and potentiometer "mechanically" in series. Make the switch part of a two stage pressing mechanism, so that you have to press "through" the switch before it can turn the potentiometer

how to regulate the pedal current on the welding machine, and not on the pedal?
