Description

This control board of spots welding machine is high power output design, 4 gears of output power adjustable, easy to adjust according to your welding requirements, and the welding process is more accurate. It supports welding 0.1-0.15mm nickel plated sheets with solid and beautiful welding spots. Two types are available, you can choose the control board only or the control board and complete accessory set according to your demands.

Features:
Working Principle: The welding process is based on the principle of high current and high temperature, rapidly melting part of the nickel sheet and cooling.
4 Gears of Power Adjustable: easy to adjust according to your welding demands, and the welding process is more accurate. 
Nickel Plated Sheets: It supports welding 0.1-0.15mm nickel-plated sheets with solid and beautiful welding spots. 
Recommended Working Power Source: 12.0V car starter power, 45C model 3S high-rate battery packs, three-string high rate lithium battery packs 409003 string battery packs, 12.0V 20-45AH or more nice performance leadacid batteries.
Power & Light Flashing: green light flashing once (every 3 seconds or so output a low power spots welding pulse); green light flashing twice (every 3 seconds or so output a medium power spots welding pulse); green light flashing three times (every 3 seconds or so output a high power spots welding pulse);  the Red light is keep on (4-speed power automatic spots welding, press about 1-second spots welding once)
Buzzer & Welding Indicator: For each spots welding output, a buzzer is briefly sounded once, and the indicator flashes green.
Optional Welding Pen & Accessories: Thickened pure copper welding pen design, with alumina copper spots welding needles to ensure high current passing capacity and durability. Complete kit of accessories, ready for use.

Note: You need to prepare your own 12.0-volt power supplies.
