Scope of application: Lead sheets of rechargeable battery can be welding rapidly. The production, installation, welding of lithium battery or mobile power. The welding of lead sheets and wires from metal parts. Specification : Material: Plastic Model: HB-70B Main Color: Orange Input voltage: 220V Maximum weld thickness: 0.2mm Power: 1900W Maximum Welding Current: 500A The pin size: 1.5mm x 7mm The aggregate area of cable: 18mm The overall length of welding pen and cable: 630mm Welding distance can be adjusted to 4-10mm. How to use it: 1. It should be grind the welding pen use fine emery paper before connect the spot welder for prevent oxidation. 2. Using the above method to deal with the copper head of spot welder. 3. Fit the welding pen and welding copper head together by the M4 spanner that should be tighten to keep well conduction. 4. The spot welder plug must insert in one power socket, don't plug in second socket, otherwise it will lead to electric current cannot supply. It will affect the spot welding. 5. Because the length of copper cable is 0.65mx2,that will reduce pulse welding current, so it must adjust the current about double times. 6. The aluminum alloy snap-in nozzle is 1.5, after wastage, that must pull out by fixture and change new welding nozzle. It must push down to low-end. 7. To assure quality, that must keep cleaning the oxide the welding nozzle. Package includeds : 1 x Spot Welding Pen 70B Details pictures :
