Welding Performance

1) Expanded Welding Applications: Maximum Welding Current of 16,000 Amperes.

This higher current capacity allows fuse welding of large parts and welding of high conductivity materials.

2) Industry’s Longest Welding Time for 16,000 Ampere Current Capacity:  Up to three (3) seconds duration.   

With up to 3 seconds welding duration, Avio’s new Model NRW-IN16K4 It can be used for resistance brazing where long welding duration is required.

Multiple Useful Functions

1) Accommodates Various Welding Requirements Based on Its Multi Control Modes

Various welding procedures, including welding quality and productivity, are easily implemented by selection of constant current, constant voltage or constant power modes.

2) Stable Welding Quality Based on Pre-weld Judgment Function

Abnormality of welded object or electrode can be detected by flowing extremely small current for a short time and measuring the resistance between the objects to be welded before the actual welding process. This avoids damage to products and to the welding electrode due to sparking.

3) Expanded Welding Applications with Increased Memory Capacity for up to 255 Welding Conditions

Multiple welding points can be welded under different welding conditions, for example, in the production of motors.

4) Input Voltage of 400 V Standard is Useful in the Global Market

Standard: 3 phase / 400 V (380 – 415 V)

Optional: 3 phase / 200 V (200 – 230 V)
