ADJUSTING THE MACHINE FOR ANOTHER WIRE DIAMETER
In all machines ALFA IN MIG / MAG are used rolls with two grooves. These
grooves are intended for two different wire diameters (e.g. 0,8 a 1,0 mm). Groove
can be replaced by removing the rolls and rotating them, or use a different roll
grooves with required dimensions.
