Purpose: welding Working mode: spot welding Drive type: semi-automatic Current: both AC and DC Acting on: metal Welding principle: butt welding Working principle: pulse Style: hand-held Machining accuracy: high power Set: one integrated pen, one small tool, thread Main output of contact welder: (Voltage 4-12v, current above 800A is preferred) Features: It is equipped with a pair of Japanese concentric ball needles as standard, with good use effect. 18650 battery spot welding pen, suitable for long-term work and improving work efficiency, is made of thickened copper bars,. The appearance is beautiful and tidy. The overall copper bar has fast heat dissipation, which is very suitable for assembling battery packs. All copper bars are cleaned with strong acid and protected to ensure the brightness of copper bars is very beautiful! The handle has double springs that can be retracted. Each welding pen is retracted independently, and the strength is controlled moderately. It will not happen that the pressure balance between the common integrated spot welding pen and the two welding needles will not lead to unstable welding, large sparks, and low work efficiency. This problem can be solved by independent expansion of double springs, which is suitable for batch spot welding production. Built in travel switch, single hand operation, no need for pedals, greatly improving work efficiency. When the pen grip spot welding handle is used, the palmaris brevis can touch a large area of the battery surface, and will not be tired due to long travel and heavy spot welding handle during long-term operation, which is very suitable for batch production. Note: This product is an integrated spot welding pen, which needs to be used by a contact welder. It is only a spot welding pen, and cannot be used alone.
