Battery Spot Welder Max 21KW Capacitor 18650 Battery Welding Machine

Heltec SW01 series spot welding machines are capacitor storage welding machines. They’re high power spot welders with max peak pulse power of 21KW. 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.
