Have a portamig 235 with a standard parweld torch which came with welder and was thinking of getting a longer torch will the 235 wire feed set up be able to push the wire through a 4 meter or even a 8 meter torch.
When I ordered my 215 from Weldequip I asked about the 4m torch and he did not recommend using one with 0.6mm wire. Having said that the Parweld at work has a 4m torch and 0.6mm wire, the limited use I have given it so far there have been no issues and I like the torch which I think is a Starparts Titanium that feels more flexible than my Parweld torch. The works welder does however have a 4 roll wire feed with a humongous motor.
My 270 oxford has a 4 meter torch no issues, but I dont own any .6 wire, never felt the need. In days go e by with my old machine, never an issue with .8, but .6 was about as much use as a chocholate fire guard.
