Features:
1) PWM and PFM control system provide constant current and precise current
control
2) Adopts soft magnetic ferrite materials for main transformer and IGBT power
components for high efficiency and economical energy usage
3) WS series is highly reliable due to its multi-protection function
4) Outstanding HF Arc striking, 100% successful
5) They are small in size, firm in structure, light in weight and portable for carry
6) With excellent arc stability when operating with small current, especially for
steel sheet welding
