Single Phase (AC) Type
- NT-5A / NRW-5A
Most Suitable for Welding Large Parts!
A single-phase AC type welding machine suits the welding to thick plate and copper stranded cable as it can adjust weld time more wide range than an electrostatic stored energy type. Its characteristic of low peak current gets little effect of dirt or stain on the surface of the workpiece, accordingly it is effective welding process when the derivation of the weld spattering and burrs, that are produced especially in the weld schedule of preheating or up slope welding, cause troubles. Power is demonstrated.
- Burr: Aprotrusion shaping like hair spring produced during welding. Fin.
- Most suitable for the automatic machines because small size and various welding function (pre-heating, up-slope, cooling time)
- The actuation control for the welding head is available by squeeze and holding functions
- Automatic switching function for 2kinds of setting conditions is provided
- A compensation circuit for the power source voltage is built-in
