DNW1 Series Pneumatic AC welding machine Features ★ one can even complete multiple spot or projection welding spot welding, higher welding efficiency. ★ configurable dual foot switch for switching between different welding specifications, that is, two foot switches control different output current and time parameters. . ★ specially designed integrated pressurized cylinder, pressurized to ensure the stability and mobility and with welding speed. ★ using the insulated conductive part of the second way to avoid accidents is easy to produce a short circuit when the insulated portion of the secondary iron or lower seat installation workpiece. ★ electrode pressurizing speed can be adjusted, slowed by the impact of the welding object pressurized, but also reduces the noise welding. ★ low impedance transformer design, the secondary loop using a high-quality conductive material, reducing internal friction, has been little input gain more welding current. ★ can store 15 welding procedures: Different welding specifications can be stored in different welding program, very easy to achieve smooth and accurate welding of different parts. ★ multipass forced water cooling system, to ensure the long-term operational reliability. ★ Widely used in metal welding wire, metal mesh, nets and other products.
