FAQ
Which battery cells can this spot welder handle?
It is specified for cylindrical batteries, including 18650, 21700, 26650, and other cylindrical cell formats.
What nickel sheet thickness is listed?
The listed nickel sheet capacity is up to 0.3mm under suitable welding conditions.
Does this machine need compressed air?
Yes. The listed pneumatic air pressure requirement is 0.4-0.6 MPa, so a suitable compressed-air source should be prepared.
Is this a handheld portable battery spot welder?
No. This listing is for a 15KVA 220V pneumatic battery spot welder with manual positioning and semi-automatic pneumatic welding action.
What should I confirm before ordering?
Confirm the battery cell format, nickel sheet thickness, air supply, 220V power setup, and welding process requirements before ordering.
