Welding inverter WMaster MMA mini 260

Welding the apparatus WMaster MMA-260 mini is a great helper for household welding. Lightweight (3.15 kg) and compact device can be connected to the mains even in ordinary apartment. At maximum welding current (215 A) it consumes only 3.5 kW. In the real MMA (manual metal arc welding) the device works with covered electrodes Ø 1,6-4,0 mm. the Inverter circuit and microprocessor control help to control the welding process from a smooth arc ignition to monitor the uniformity of the weld pool depth throughout period of work. IGBT-transistors, replacing a massive scheme transformer winding, high efficiency (89%) and almost no overheat. The reliability of the cooling apparatus includes a fan, also, there is a protection against overheating and overcurrent. Resistant to extremes supply voltage +/-25%.
This unit is designed to work in industrial environment or for professional use (respectively normal CISPR 11).
The inverter creates a uniform the depth of the seam even in unstable power grid (220V±20%). The degree security apparatus IP23 means protection from penetration the device for long items and from the effects vertically falling on the body droplets of water.
Included are welding cable with holder and ground, a shoulder belt for carrying.
