I was thinking it should be in pedal mode, so that it would operate in 2T.
Since he never got back to us, it's kind of moot.
Not clear to me what Eastwood means by pedal vs. panel and/or if that changes the 2T/4T or just allows the switch to operate properly? In theory the switch and pedal should be the same, other than allowing for amperage control with the pedal.
Still, it would be a nice gesture to update everyone.
On the eastwood, "panel" simply switches the amperage control from the foot-pedal to the front panel of the machine. In that machine, the foot-pedal has it's ownpotentiometer that you must utilize if you wish to use the foot-pedal.
Never owned an Eastwood, but I do believe you mentioned you had at one point. However, it usually isn't that simple. The torch switch is most likely a 2 pin connector, whereas the pedal will typically be anywhere from 4-8 pins. That panel/pedal switch, in addition to shifting amperage control, also has to tell the microcontroller what signals to expect and what signals to deliver based on the inputs. And if you're in the wrong mode, and start sending unexpected signals to the micro (or fail to send expected signals) you'll start to see some odd behavior from the machine, much like the user was seeing. A lot of the odd behavior you may see also depends on how well the code was written that controls the micro. Well written code may present no issue at all when in the wrong mode, very poorly written code may result in you blowing fuses or burning up components. But usually it will be something in between those extremes.
Edit: And even if both the torch switch and the pedal are 2 pin connectors (which I doubt a bit), you would still be changing the expected signals to the microcontroller based on the position of the "pedal/panel" switch. Anomalous behavior from the machine would still follow.

Why do you think I got rid of that thing, lol. The whole amperage on the pedal thing wasn't all that great. Bought my 221 in Nov/Dec 2013 and never looked back, lol.
I'm just thinking ... (note, this is gonna be dangerous) ... the pedal mode goes to full tilt with amps and controlled with the potentiometer being the max adjustment. And the panel mode, you can adjust the amps on the "panel" with the torch button having ramp up and ramp down built in without adjustment.
