Battery Spot Welder HT-SW02H 42KW Capacitor 18650 Battery Welding Machine

Heltec new spot welding models are more powerful with max peak pulse power of 42KW. You can select the peak current from 6000A to 7000A. Specially designed for welding copper, aluminum and nickel conversion sheet, SW02 series support thicker copper, pure nickel, nickel-aluminum and other metals welded easily and firmly (support nickel plated copper sheet and pure nickel direct welding to the battery copper electrodes, pure copper sheet direct welding to the battery copper electrodes with flux). HT-SW02H is also capable of resistance measurement. It can measure the resistance between the connecting piece and the electrode of the battery after spot welding.

Note: This machine can be shipped from our Poland warehouse, contact us before your order so we can check if it’s in stock. You can send an inquiry first if you want to get the best deal.
