AC/DC Decisions

I bet if you was to put a parweld plug on an ssc pedal (with correct pot rating) it would work like you want it to.
Edit but confirm with someone more knowledgable like Jim before going down that road.

 

[Gizmo.Y]

Im going to be bloody annoyed if i have to purchase a new pedal for it...As i paid the extra for the pedal.

IIRC, the Pedal has a total of 6 or 7 pins in the plug.

 

[Xup]

Is it Parweld's own pedal or a 3rd party one ?, any option to contact the supplier and swap out for a pedal with out the outside pot.
As I see it now it's not really fit for purpose with the pedal as it is.

Hope its an easy fix for you.

There might be 6 or 7 on the plug but only 5 will essentially be used . You won't have to buy another pedal. You could return the one you bought before getting another. If you take the cover off it and photo the guts it will be easy to see if it is a simple case of bypassing the pot. If there is a circuit board in there then it's more complicated and your stuck with it but I doubt there will be.

Mine also has a 7 pin plug. 2 are not connected, is imagine yours is the same. Out of interest does it have only 1 plug and you can't have the torch and pedal connected at the same time or is there 2 plugs.

Just one socket, a 14pin affair of which 5 are used for the torch with the 3 button insert or the switch/pot setup, sounds like maybe more are used for @Gizmo.Y pedal.

Here is the wiring diag from the manual and although it says the top is for foot I suspect it is different with the pedal @Gizmo.Y has. It may however be possible to connect it that way and if so then it should work just the same as the torch with button/pot.

 

[Richard.]

I don't think there will be hood.
The same 5 pins used for the torch will be used for the pedal.
It might have a 7 core cable on it but I can't think of any reason for 7 to be used.
It will work in the same fashion as the torch. Switch and pot.

Yep exactly as I thought. 5 cables for both.
Giz this is a simple thing to do.

Hopefully it is just a case of connecting the switch direct but I have a nagging feeling it may be using more pins.

 

[Gizmo.Y]

I still want the potentiometer in the pedal to work, i just want to be able to set the min and max amperage on the control panel

The switch is connected directly . The switch isn't the issue it's the second pot that is taking over the control.
What other wires do you think there are then?
I can't think of any and your drawings confirm it.

When using the torch controls hood can you set the current from the machine using the main dial with the torch plugged in.

Not sure about min but you'd be able to set the max. Min would likely be the Lowest setting on the machine. So you start up at 5 amps and your max would be whatever you set on the panel.
But I don't know this for sure.

With the pot it takes over totally and you can not adjust from the machine, with the UP/Down switch insert connected then yes, can alter from either torch or panel. So looks like because the switch insert only makes contact when you press then it allows you to control the current from the panel.


There is more going on than just that however. If you hold the up or down button it will step up in 10's, so obviously it is capable of differentiating between a pot and momentary switches being connected even though they use the same pins.

I am thinking possibly there are extra connections for setting Max but as I don't have a pedal I can't say for sure.

 

[Richard.]

We'd need to see the pedal guts to confirm I think.

Or maybe the pedal manual has a pinout. I don't have one as I don't have a pedal, maybe I can find one on Parwelds site though, will look.

 

[Hood]

Can't seem to find a manual

 

[Richard.]

Is it not the same as the diagram you posted up the thread then?
