Product Details

Product Description

Product Features:

Uses high power MOSFET to convert industrial frequency (50/60Hz) into high frequency (>100kHz), which is then reduced and rectified. The product can then output high power DC source with the use of PWM technology. The main transformer can thus reduce dramatically in size and weight, with the efficiency enhanced by more than 30%.

1. Auto compensation against power fluctuation, stable welding current.

2. Protection against over-voltage and over-current.

3. High arc-force.

4. Small and light, high efficiency.

5. Applicable to different acidic and basic electrodes.
