This product is an integrated spot welding pen, which needs to be connected to a spot welding machine. It is only a spot welding pen and cannot be used alone. Each welding pen is independently extended and the force is controlled moderately. The ordinary integrated spot welding pen cannot balance the pressure of the two welding needles, resulting in loose welding, large sparks, and low work efficiency. The use of double springs to independently extend and retract solves this problem, which is suitable for batch spot welding production. Internal extension solves this problem, which is suitable for batch spot welding production. Built-in travel switch, one-handed operation, no longer need a foot pedal, greatly improves work efficiency. When the hand uses a pen-style grip spot welding handle, the palmar brevis can touch a large area of the battery surface. When working for a long time, it will not be fatigued due to the long stroke and heavy spot welding handle, which is very suitable for batch production.
