Wire Welding Machine / Reinforcement Steel Welding Machine (Nippon Welder Co.,Ltd. / Nichiyo)

We deal with the NICHIYO brand welding machine manufactured by former Nippon Welder Co.,Ltd.
Members who have inherited the drawings and knowhow from Nippon Welder Co.,Ltd. are providing welding machines that are exactly the same as the conventional machines.
We also sell components.

【対象形状】  棒材
【電源仕様】  200/220/230/240VAC、50/60Hz、単相(380/400/415/440特注可)
Brazing is performed through direct resistance heating of the target object, such as the wire material, sheet material, and pipes.
This not only helps realize high productivity through energy conservation as compared to other brazing methods, but has several advantages such as no pollution, no need of skilled operators, high safety, and a low running cost.
