The Fubag IR-200 welding inverter operates with a high limiting current of 200 A, which makes it possible to operate it not only for welding, but also for cutting metal with electrodes of all varieties up to five millimeters. In this case, a wide range of operating voltages is observed. The equipment is able to work when the indicator drops to 150 volts, which is important for rural areas, where current surges are not uncommon. Facilitates the operation of additional functionality in the form of anti-stick, hot start, afterburner options.
The advantages of the unit include:
- solid current margin;
- continuation of work at significant voltage drops;
- additional modes that facilitate ignition and arc.
Among the shortcomings is a weak coefficient of PV (40%). This indicator causes a short duration of continuous operation (every four minutes it takes about six minutes to cool).
