| The LAW 420 and 520 MIG/MAG power sources
belong to the A10 range. These welding machines are designed
for heavy use, in- and outdoors. They are equipped with
large wheels, sturdy lifting eyelets and the carriage is
specially designed to be lifted with a fork-lift truck.
The power sources LAW 420 and 520 offer a wide current range
and work excellently with mixed gas and CO2 shielding gases.
They are optimized for cored and solid wires. Some models
have a built-in water-cooling system. The operator can weld
up to 65 meters away from the power source with an intermediate
feeder and extension cables. To be close to the welder the
voltage control, wire feed speed control and crater fill
function are located on the wire feeder.
Delivery includes
5 m of mains cable, wheels, return cable with clamp, cable
connectors, gas bottle platform and a guide pin for the
wire feeder.
