Features of MZ-B series submerged arc welding power supply

MZ-B inverter series submerged arc welding machine is an efficient and energy-saving arc welding equipment using IGBT inverter technology. It is suitable as a power supply for submerged arc welding, manual arc welding and gas shielded welding. This power supply is versatile and suitable for a wide range of industrial applications.It can weld carbon structural steel, low alloy structural steel, stainless steel, heat-resistant steel and its composite steel, etc.

1. The welding current can be preset.
2. Small size and light weight.
3. It has the function of slow wire feeding arc ignition and wire retraction when welding is finished.
4. The current adjustment range is wide and can be used for submerged arc welding and manual arc welding.
5. The efficiency and power factor are high, so there is a significant power saving effect and a high grid utilization rate.
6. The IGBT inverter technology is used to ensure that the welding specifications are highly stable when the grid voltage and arc length change.
7. When the wire is fed in an inching manner, the wire automatically stops feeding when it contacts the workpiece to prevent the wire from bending and affecting the arc ignition. The wire can be forced to feed when the wire is bonded to the workpiece.

Features of the WT-MZ Welding Cart:

This welding cart uses a lead screw and nut for horizontal adjustment. The slide guide structure is integrated with the base, resulting in a low center of gravity, ensuring stability, reliability, and smooth, flexible adjustment. Vertical feed utilizes a lead screw and nut and slide guide, with a bearing-equipped rotating shaft for flexible rotation. The structure is simple and easy to operate. The wire feeding geared motor and cantilever arm are integrated, resulting in lightweight construction, a reasonable center of gravity distribution, and a neat appearance, increasing the stability of the welding cart during the welding process. The column has a large lifting range and flexible operation; the conductive rod can be extended arbitrarily; the improved nozzle tee structure and easily machined conductive nozzle further facilitate the welding of H-beams, plates, and pressure vessels.

Specifically designed for use with the MZ-B inverter submerged arc welding machine. Current, voltage, and welding speed can be preset. During jogging wire feeding, the wire automatically stops feeding upon contact with the workpiece to prevent wire bending and interference with arc ignition. Forced wire feeding is possible when the wire adheres to the workpiece. Suitable for electroslag welding and submerged arc welding processes, featuring slow wire feeding for arc ignition and wire retraction at the end of welding. Automatically compensates for grid voltage and arc fluctuations, ensuring stable welding process parameters.

Applications:

The MZ-B series power supply is ideal for industries requiring high-efficiency, precision welding in heavy machinery, shipbuilding, steel structure fabrication, pressure vessel manufacturing, and pipeline welding. Its stable performance and energy-saving design make it a reliable and cost-effective choice for large-scale industrial welding operations.
