Spot Welding Machine

Battery Spot Welder 12KW Capacitor Storage 18650 Battery Welding Machine

Heltec spot welding machines are capacitor storage welding machines with safety certification. They’re high power spot welders with max peak pulse power of 19.8KW. You can select the peak current from 2000A, 2500A to 3500A. It is easier for you to use the correct spot welding mode with the dual-mode function key on them. You can measure the connection on-resistance separately by precision micro-ohm resistance testing instrument. They can reduce labor intensity and improve efficiency with AT intelligent induction automatic trigger discharge. It’s easy for you to view the parameters with LED color screen on them.
