The machine is very helpful in making the widening of steel wheels, for the drive I used an electric motor with a gear, the engine speed was additionally reduced so that it was possible to weld not only with the mig method but also with the tig method. With such a widening of the wheels, work must be done very carefully, without haste, weld with high current to perform remelting. The wheel that I widened is much harder to widen than the regular wheel, but thanks to the rollers, I managed to make this wheel perfectly, the rollers help to center and align the wheel axis
