About this item 【Concentrated energy pulse welding】801A adopts the latest energy concentrated pulse welding technology, the welding effect is good, the power is large, and the solder joints are beautiful and generous, ensuring the welding effect is reliable. 【Battery spot welder】Compared with the traditional AC spot welder, the newly designed 801A capacitor energy storage spot welder has no interference to the circuit and no tripping problem. 【2 welding modes】Equipped with 70B mobile welding pen, 73S hand push welding arm and "AT/MT" two welding modes, the welding work can be completed easily and efficiently, and the welding points are beautiful and generous. 【Pulse Welding】The pulse welding power can be conveniently set by two adjustment buttons (range 0-99), and directly displayed on the panel LED screen (display welding power/capacitor voltage/actual welding current). 【Easy to carry】The portable welding machine is small in size, light in weight and easy to carry, while still using a wide voltage input of 100-240 V, which can be used anywhere it is needed. It is smaller and lighter than traditional large heavy-duty spot welders, yet more powerful and reliable.
