LED Lighting Function 

LED lighting type enhanced version, ensure precision electric welding in low brightness environment. The welding electrode is welded with double LED high-brightness lighting device, and the welding operation is clear at a glance. 

Accurate Welding Pressure Regulator 

The welding pressure regulator of the professional welding machine, the welding pin pressure can be continuously adjusted from 300g-750g to facilitate the welding of workpieces of different thicknesses, to obtain good and reliable solder joints. 

Multiple USB Output Ports 

788-USB has a three-digit USB output port with an output capacity of 3A, which can be used for charging aging and testing for three charging treasures at the same time. 

Pulse Group Setting Knob 

The 788H-USB combines a knob-type quick-set pulse group (16-pulse) high-current slow-speed welding mode, which is suitable for thick-cell battery nickel sheet soldering. 

Additional Accessory 

A 1Kg nickel plated steel strip is in the tool kit. The 788H-USB battery pulse spot welder comes with a complete accessory for you work.
