MIG-MAG welder Welbee W400

ACpulsed DCportable

New power source Welbee W400 for high-speed AC pulse welding The latest addition in OTC DAIHEN EUROPE GmbH product range for the AC / MIG process of is the new Welding Power Source, Welbee W400, which is responsible for optimal control of the energy input, the high shrinkage rate and the firing control. It replaces the previous model, DW300 +. While the arc is burning, the Welbee W400 can alternatively switch the welding processes to either AC pulse, DC pulse, AC wave-pulse MIG or DC wave-pulse, during the welding process.   Automation processes for the processing of aluminum alloys are regularly tested. Conventional welding methods frequently fail because of the fact that during the welding process, warping or inadequate gap bridging occurs. In recent years, OTC’s pulsed MIG AC welding process (abbreviated as AC / MIG) has been used to improve the quality of the arc welding process. Using the so-called wave-pulse function, the control of the welding current is precisely synchronized with the wire feed speed in the AC / MIG welding process, in order to optimally control the weld pool. Even in the case of galvanized steels which are prone to the formation of pores, the number of pores can be considerably reduced by using the so-called wave-pulse function. The AC / MIG process allows for a much lower or controlled insertion depth with a low welding current, a constant welding speed and an unimpeded feed rate.
