Review on SUNKKO 737G+ Battery Spot Welder, Pulse Welding Machine for Lithium Battery Pack, Compatible with 18650 and 14500 Batteries, Works with 0.35mm Nickel Strips, 110V by Paul Hyde

Revainrating 5 out of 5

It worked well until it didn't work at all.

I had this machine and have successfully assembled several battery packs. It takes some tweaking to get a decent weld, and the electrodes burn out pretty quickly. My big problem is that after welding 175 battery cells the device doesn't work. I thought I was ok because it's the "top of the line" Sunkko. Should have found out. Save yourself the headache and get Kweld from Germany, much better.

Pros
  • Welding and soldering
Cons
  • Almost everything is fine
