Ewm foot pedal

[bletchmonster]

I like that idea Richard! The tig (my precious) lives on racking well away from the destructive environment of the welding bench, so a remote amperage pendant has definite appeal.

That’s not an amperage pendant on mine. It’s a pot that interferes with the second pot in the pedal.
I’m not suggesting you do this unless you know it’s gonna work but how mine worked was when the pedal was off it displayed main current which you would pre set as your max pedal current. Then when you turned the pedal on your display showed what the remote pot was reading which was start up current. I’m trying to find the picture of the drawings so you could look at copying them.
Obviously always consult with jim first before you start chopping wires. Because ewm could have differences but I’m sure it’s possible to do what I’ve done.

I still think you could of got a few more Tweco stickers on that cooler @Richard.

Maybe but I wanted to keep it quite plain

This thread is the reason I'm subbed to this forum. Also have a 230 Tetrix from EWM that I bought few years ago. Would like to try and switch to a new torch like CK one's because multiple reasons. But that requires running a pedal. And a pedal requires to switch to was it 8 contact control plug. I think this whole conversion requires nearly a thousand moneys. And this time I'm not that good with finances. So what is a ballpark for those SCC pedals you mention in this topic? Any place I can see them? Or are they the same ones on ebay for 300ish for EWM? Thanks.

Shouldn’t be anything like a grand for a torch and pedal mate.
Speak to Jim Davey. He builds SSC pedals to go straight on ewm machines and despite the fact they are cheaper, imo they are a much nicer pedal. I can’t stand the oem ewm pedal I think it’s an awful lump to use.
I’m assuming your machine is gas cooled so a ck torch is gonna be cheap too.
A ck 17 with flex cable and sheath should come in easy under the £200 mark. You’ll do the whole lot and probably have change for a pint or two out of £500 I’d imagine.
If you get Jim to build you a pedal you may as well ask him to price up the lot.
He built an ssc for me some years back and it was proper job.

I might be off on pricing slightly as its the information from nearly a year back, but I think it was something as ~100euros for 8pin socket to go on the machine, then 4 or 5 hundred for ewm pedal from local dealer. CK torch with consumables from the states is something like 300eur+vat or something like that. I need the whole lot of consumables as currently am using binzel gas lens torch. That uses "unique" consumables, that will not work with ck stuff.
If there is no listing from Jim Davey, I'll message him to see what he can offer on this. Cheers.

you plug the pedal in the rear 19 pin socket , comes on every Tetrix machine

 

[CrazyTheCrip]

Ah, so it appears that I have some wrong information from somewhere. This is nice to know that 8pin socket is not required to run a pedal.

PM replied to. I’ll look into pricing a CK torch for you tomorrow

New to this site and TIG welding, just bought a used TIG set and am getting to grips with it slowly. Great info found on here especially finding out a pedal connects to the back of the machine, (EWM Tetrix 200 MV) not in place on the torch switch!
Cheers all
Bobby

 

[Jim Davey]

Do you need a pedal or 5 pin torch plug?

 

[Marty J]

I need to order a 19 pin plug for my EWM Tetrix, does anybody know what type it is ?

 

[brockenhammer]

Hi,
it´s Burndy.

 

[Jim Davey]

We stock them, but only with the crimp pins not the solder type. You can pick up the crimp tool relatively cheaply online.
I’d not recommend trying to crimp the pins any other way as they get chewed up very easily.

Resurrecting this. PM'd

Link wires J and M in the pedal, not at the plug. I take a link from the leg of the pot J wire and go to the side of the micro-switch that joins the M wire.

J Goes to 10 K pot

C is pot wiper

F Goes to 10 K pot

R and M are connected to the switch

A goes to ground via a high voltage 1000v plus 2.8nF capacitor.

If you've got it right, with multimeter set to ohms and your probes on pins C - F, set the pedal in the up position and your meter will show around 10 K, then with the pedal depressed read Low ohms. Don't worry about the 10 ohms minimum bit, the resistance in the cable and the pot contacts will nearly give that on their own.

EDIT: Had a closer look at my drawing and the link is the key part, do it in the pedal, not the plug.

Hello Jim,
Just purchased the Tetrix 230 comfort 2.0 5p and i am looking for a quality pedal.
Reading this it seems you are the man to talk to.
I am in the UK for the next 3wks before returning to India. Do you think you can get one to me before the 12th of September?
Thanks
Graham

 

[Jim Davey]

Certainly Graham, I think I have 3-4 left in stock. PM me your contact details and address and I’ll send over a quote on Tuesday.

Thanks
