Aluminum Plate Welding Machine Medium Frequency Spot Welder

DESCRIPTION

Medium Frequency Direct Current machines use an inverter, powered from a 3 phase supply in which the current is rectified using diodes and then chopped by means of IGBT’s into high frequency alternating current. This alternating current is then transformed by the welding transformer and again rectified. DC current is thus obtained at the secondary side in to the parts to be welded.

The MFDC welding machine load is evenly distributed across all three phases. This allow equal load to be drawn from each line, thus reducing peak draw on any one line. The price of MFDC machines is higher than the conventional Alternating current (AC) machines but users will get advantages such as three phase balanced loading, weight reduction in transformer, about 20 to 25% less power requirement as compared to AC machines, better control over time and uninterrupted energy input into the parts to be welded.

FEATURE

Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.
Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality
Three phase load balance, power factor is close to 1
Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine
Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
Smaller size and lower weight of welding transformer, one third of the AC machine .
Be able to weld aluminum and galvanized material product
Especially suitable for welding three-layer metal sheet or very thin product
