1.1.1 WT-MZ Submerged Arc Welding Trolley

1.1.2 MZ Series Submerged Arc Welding Power Supply

Competitive Advantage:

Features of MZ Series Arc Welding Power Supply:

MZ series submerged arc welding power supply adopts thyristor control technology, which can quickly and automatically compensate for network fluctuations,to ensure the stability of the arc and convenient adjustment of the output current. The introduction of the three-phase circuit minimum trigger angle protection control method
can better control the dynamic characteristics of the power supply. Therefore, this equipment can also provide DC output for steelmaking and rapid quenching equipment, which better makes up for the shortcomings of the first generation of products and is particularly suitable for submerged arc welding processes with variable speed wire feeding.

1. This series of welding machines is mainly used for welding various steel plate structures with grooves or no grooves, lap welds, fillet welds, etc. This type of weld can be located on a horizontal or inclined surface with an inclination angle of no more than 10 with the horizontal plane. It can weld carbon structural steel, low alloy structural steel, stainless steel,heat-resistant steel and its composite steel, etc.

2. This series of welding machines fully adopts the latest technology and components, and has stable operation and convenient operation. Its main performance is much better than the old MZ-1000 and MZ-1-1000 submerged arc welding machines.

3. It is especially suitable for welding H-beams and plates in the steel structure industry.

WT-MZ welding trolley features:

It can be used to weld butt welds, lap welds, fillet welds, etc. Such welds can be located on a horizontal plane or an inclined plane with an inclination angle of no more than 10° to the horizontal plane.
The types of steel that can be welded include carbon structural steel, low alloy structural steel, stainless steel, heat-resistant steel and its composite steel, etc.

1. It is small and flexible, walks smoothly, and can be used in a variety of welding scenarios.

2. It is equipped with a horizontal and longitudinal adjustment mechanism and a wire feeding mechanism with multi-angle displacement, which is easy and flexible to adjust,suitable for multi-position welding.
