Portable Battery Spot Welder Welding Machine with Shell For 18650 Lithium Battery Nickel Sheet

Features:
– Aviation aluminum alloy shell is drop-resistant, ensuring safety. Surface anodic oxidation process, the shell is beautiful and wear-resistant.
– It is easy to remove welding pen for easy carrying. Gold-plated terminals have a long service life. Anti-oxidation welding pens are easy to disassemble and install, and easy to carry.
– Compact size makes carrying easier. The size is similar to the size of a cell phone.
– Universal Micro USB charging port is compatible with mobile phone charger. 5V 1A input. It can be fully charged in 4 hours.
– Gold-plated solder pen terminal features low internal resistance and oxidation resistance. Red copper pen holder, copper oxide aluminum welding pin, using cold pressing process.
– With ultra-low internal resistance, 2mm thickened pure copper over-current bars increase over-current capacity.
– Imported MOS tube. A single continuous current is 300A. The designed maximum current is 1200A.
– High efficiency power. The internal resistance of two power supplies in parallel is less than 0.9mΩ, and the discharge current is greater than 639A.
