hand-held integrated spot welding pliers upper and lower butt welding pliers

Description

Hand-held integrated spot welding pliers Upper and lower butt welding pliers Spot welding pen Lithium iron phosphate battery assembly Aluminum ear to nickel sheet
model:
16 square wire spot welding handle (not including welding pins)
A pair of 3mm alumina solder pins
A pair of 3mm Japanese alumina solder pins
Nose joint hole diameter 8.5MM, main copper rod diameter 8MM has 50 square MM. Tact switch: Maximum 12VDC 50mA, only suitable for the voltage or current signal of the original welding machine, can not directly drive the electromagnetic relay, the switch pay attention to waterproof.   Applicable universal pin diameter 3MM solder pins. 25 flat line handle total length of 750MM or so, line length 600MM The total length of the 16 flat line handle is about 650MM, and the line length is 500MM.   It is normal to have small scratches and glue marks on the sides. Solder pin The wrench is only taken by this wrench. Advantage 1: The main copper rod is made of copper. The copper content of copper is more than 99%. It is also called copper and copper. It is comparable to non-brass. The copper content of brass is only 62% and cannot be called pure copper. The conductivity of copper is 3-5 times that of brass. The spot welding power is larger and better, and it is more stable.   Advantage 2: The handle is designed in one piece, and the current is once to the point.   Advantage 3: With a tact switch, one-handed operation without a foot pedal.   Advantage 4: The clamping needle is tightly held, which is convenient to change the needle, does not hurt the needle, and has a large contact surface. How to distinguish between copper and brass: The copper color is red, the brass color is dark yellow. In addition, the hardness can also be distinguished. The copper is soft and the brass is hard. It is sanded with sandpaper or steel balls. The yellow is brass, and the red is red. Copper.   The direct-injection quick-connector of the spot welder is a non-interference fit with a large gap. It is stuck by a misalignment, and the contact area is small, which reduces the passing current. 0.0 seconds through hundreds of thousands of amps of current, all joints should be tight and elegant. A quick connector with a resilient contact surface can be used. The best is the copper nose connector plus screws.    Copper nose and joints do not use the machine screw top do not solder! The top wire will only be partially stressed, and the actual contact surface is less; the resistance of the solder is larger than that of copper. When the current is high, the tin will heat up and it will melt seriously. This is the principle of resistance welding. It should be crimped with professional hydraulic equipment, the force is even, and the surface is smooth, which makes the contact surface larger. The complete set includes spot welding handles, flexible wires, and copper noses that have been installed.   Spring, switch, positioning, copper rod, copper nose, wire, shell once crimped to complete the installation, do not sell parts. Wired friends can send me a cable to install.
