Frequently asked questions
Can I use it without a spot welding machine?
No. It is a pen that connects to a spot welding machine, so check that its connector and the machine's settings are compatible before use.
Is it safe to spot weld 18650 cells?
Spot welding can damage cells if the energy or timing is wrong. Use protected cells where possible, follow the machine's settings, and work with care around lithium-ion batteries.
