Hi,
the newer Fronius pedals (TR2200) use canbus. The older ones (TR52) not, but there is a little board inside, so connecting another pedal to a Fronius machine is very complicated.
The EWM Pedals use the conventional style with pot and switch.
I bought myselg a magicwave 2200 but i noticed that the torch is connected to canbus foot peadal port though i have at work one that uses that white adapter for torch. Could somebody explain this
I bought an aftermarket footpedal for my MW2600 from ebay
The fronius version was another £50(ish) over the same pedal for other machines
I will open it up and take a photo of the board
