Advantages

1. Features of MZ-E series arc welding power supply

MZ-E series inverter submerged arc welding machine is an energy-efficient submerged arc welding equipment using IGBT inverter technology, suitable as a power source for arc welding, manual arc welding and gas shielded welding. It can weld carbon structural steel, low alloy structural steel, stainless steel, heat-resistant steel and its composite steel, etc. The rated welding current of the welding machine corresponds to the corresponding rated load duration rate. When the load duration rate increases, the maximum output current of the welding machine decreases accordingly. For example, when the load duration rate increases from 60% to 100%, the maximum output current is 0.7746 times the rated welding current.

1. Using IGBT inverter technology to ensure that the welding specification is highly stable when the grid voltage and arc length change.

2. High efficiency and power factor, thus having significant power saving effect and high grid utilization rate.
