The new ERGOPLUS family covers a wide range of Amperages (from 150 A to 600 A, air and water cooled) and includes different options: manual and automatic; for standard generators; for new generators offering the torch remote control of different welding parameters and regulations, or program recall directly on the torch; fixed torch body; some models offer flexible torch body as well.
I ended up with the light weight contact tips. I'm not sure if I ordered the wrong kit but I didn't see an option for the heavy duty units which came with my ergo 24. The rest of the parts will work but these contact tips are too short.
