12AWG Spot Welding Pen Set for DIY 12V Spot Welder

The 12AWG Spot Welding Pen Set is a high-performance accessory designed for DIY 12V battery-powered spot welders, such as the DHJ6633 control board. This set includes two color-coded pens (red and black) equipped with ultra-flexible, high-temperature 12AWG silicone wire. The welding pens feature solid copper tips that provide exceptionally low resistance, ensuring maximum current transfer and clean, reliable spot welds on nickel strips without overheating.

Perfect for makers, students, and professional hardware engineers, this welding pen set is ideal for assembling custom lithium-ion battery packs (including 18650, 21700, and 32650 cells) used in e-bikes, power banks, and robotics. The cold-pressed ring terminals on the opposite ends allow for a secure, low-loss connection directly to your spot welder PCB or power source, making it a must-have for any DIY battery building project.

Features:

• Ultra-Flexible 10AWG Wire: High-quality silicone insulated wire rated for temperatures up to 200°C.
• Low-Resistance Copper Tips: Solid copper welding pins minimize voltage drop and maximize instantaneous current delivery.
• Secure Ring Terminals: Cold-pressed O-type copper terminals ensure a robust, low-loss connection to your welder PCB.
• Color-Coded Polarity: Distinct red and black cables prevent wiring mistakes and ensure safe operation.
• High Current Capacity: Engineered to handle the high pulse currents required for spot welding nickel strips up to 0.15mm thickness.

Package Includes:

1 x Red Spot Welding Pen with 12AWG Wire
