A Portable Spot Welder is a compact welding device used primarily for joining two or more metal sheets (usually thin gauge) at localized spots without the need for filler material. It’s widely used in automotive repair, battery pack assembly, sheet metal fabrication, and electronics.
- Portability – Lightweight, handheld, or compact benchtop units for ease of use anywhere
- Power Source – AC mains, battery-powered (for cordless), or capacitive discharge systems
- Welding Current – Typically from 1000A up to 5000A+ depending on the model and use case
- Control System – Manual, foot-pedal, or microcontroller-based timers
- Electrodes – Copper alloy tips (replaceable), designed for longevity and heat resistance
- Material – Compatibility Mild steel, stainless steel, nickel, and battery tabs (nickel-plated steel)
- Welding Thickness – Usually for 0.1mm to 2mm metal sheets
- Cooling System – Air-cooled or water-cooled (for industrial types)
