Frequently asked questions
Which materials can it weld?
It is intended for nickel strips on lithium battery cells. Check the manual for the supported electrodes and strip thickness, and do not attempt to weld materials outside the stated specification.
What safety steps should I follow?
Work on a non-flammable surface and wear eye protection. Do not weld damaged, swollen or overheated cells, and practise on scrap nickel first to set the pulse level correctly.
