The maintenance free brush-less motor with the WP4 enhanced version gives it high performance and durability, with overall performance far superior to that of comparable products.

One machine realizes welding in multiple scenes, with a wide range of applications, which brings higher efficiency to welding.

Adopt closed-loop control technology (digital display + main board control) to ensure stable parameters and ensure the overall welding quality.

Small and flexible, light weight, high power.

The welding width is 40mm, which can meet the customized service of different widths in small batches.

Small orders accepted.

 To meet small batch customized services.
