2010 Itig 200 foot pedal

[Rocrat]

Hi all ,
I just purchased a new old stock 2010 Itig 200 120/240 volt machine and am wondering if anybody can tell me what the pedal resistance is ?
I have both a stock and SSC pedal for my EX 250 and wondered if I could use it on the Itig 200 .
If I can't , how easy is it to convert the EX250 stock pedal to work ?
Regards Troy

If it will plug-in, I would just try it...

Here's what I found (and shows how little understanding I have of all this)

I "sniped" a new CT520 on eBay a few years back for @$300 and it didn't come with a pedal. Pedals are like $100 and I didn't want to invest another buck into it (I got it for the Plasma more than the DC Tig) But ended-up liking it and wished it had the pedal. SO, I set out to find a cheap one thinking "it's box, spring, rheostat, pedal & plug, I can make anything work by changing the pot and pin configuration" because I couldn't get a straight answer about what this welder needed (it's a Simadre)

I opened it and checked the pot on the machine that controls the Amperage, it was 1K/2W. I ordered a 7pin "Stalwerk" pedal for $50. I opened it and found it had a 10K pot coming in and a 2.2K pot on the pedal. I assumed what was going to happen was, with the 10K turned out of the picture, I would reach 200A at 1/2 pedal travel. So, looking at both the open machines connections and the open pedal connections (sw, wiper, Hi/Lo) I reconfigured the plug and thought I would just Try it.

It works perfectly!

The 10K controls the Max and gives a finer "resolution" to a lower spread and I get Full travel control to 200A.

I don't under stand WHY? This whole "pedal resistance" might not be what you think it is

Hey Blaster ,
That's all well and fine on certain analogue type control systems , but with digital type control systems like in a lot of inverter machines , you can destroy the control circuits by using the wrong components . As far as I know the Everlast machines run on TTL logic which uses +5 to-5 volts which is not much so a foot pedal pot of double what it should be could do some damage ,which I don't want to do .
I know my EX 250 pedals are 47k , I just want to know what the Itig 200 is as the manual has conflicting info , one page it's 47k the other is 22 k .
