Quality MachineReview by Dan
Bout this machine from eWelders back in May. Good to deal with and have been able to get me parts. I do body work and other bits on pieces on my car and have a little side business going work on some mates cars. This machine has been a warrior so far. Use it a lot on aluminium and it produces high quality welds. I haven't needed the foot pedal so far because the torch has adjustable amperage. I use the down slope feature a lot for controlling the amps at the start of the weld. Really good. (Posted on 23/01/15)
