737G+ is a big improvement on the basis of 737G. It is specifically designed for battery welding (18650, 14500 and any other lithium batteries, etc) and can be used to weld nickel strips with thickness between 0.05 and 0.35 mm for nickel plated steel or between 0.05 and 0.25 mm for pure nickel strip.
Please read manual carefully before using it.
There are three ways of welding:
Fixed welding head with foot pedal: You can build your battery pack with the fixed welding head and foot pedal. Coordinating hands and feet at the same time will make the long-term welding process not so tiring, plus the use of foot pedal during battery welding improves the precision of spot welding. In this welding mode, you need to adjust the pressure adjustor to make the spots more reliable and elegant.
Mobile welding pen with foot pedal(MT): The mobile welding pen effectively extends your welding area, and this design is popular among electric hobbyist, because they can build large lithium battery packs for their e-bikes or other projects.
Mobile welding pen without foot pedal(AT): In this mode, you need to unplug the foot pedal first. Once the welding pen attaches nickel strip, the welding pen will release the energy and weld automatically, you just need to give a little pressure to the pen just like you are writing.
In general, there are two methods to improve the output power of spot welding: adjusting welding current level through current knob or adjusting pulse quantity. You may need to play with them a bit to get the best combination for your specific use.
