This electric welder completes the inter-cell connection weld and short-circuit test.
After the COS and plate insertion, the battery is conveyed to the short circuit test station, automatically positioned and stopped. If short circuit is detected, the machine will alarm, and the battery will be rejected; qualified batteries are delivered to the inter-cell welding station. If the welding process works abnormally, unqualified batteries will be rejected. If the welding condition is qualified, the batteries undergo another short test before being delivered to the next station.
