Summary
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.
(Attention: When the foot pedal is plugged in, it’s in MT mode, otherwise, it’s
in AT mode.)
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.
Welding range: 0.15~0.35mm for nickel plated steel, 0.12~0.25mm for pure nickel
strip;
Preparation steps:
1. Fit the fixed welding head with copper welding rods before the machine
powers on.
2. Plug in foot pedal.
3. Turn on the main power button, and then the welding power switch.
4. Adjust the pulse quantity and welding current level to make the spots
more reliable and elegant.
5. Weld your batteries with fixed welding head along with the foot pedal.
