The Tooltos 80A Pulse Jewelry Spot Welder uses plasma high-frequency discharge to instantly form a molten pool at the weld joint — delivering smooth, firm welds on platinum, gold, silver, and steel without welding powder. With an 80A output and 0.5–1.5 mm welding range, it handles a wider range of wire sizes than the 30A and 50A models, making it suitable for both fine wire and medium-gauge jewelry applications.
Key Features
Plasma High-Frequency Discharge — Instantly forms a molten pool at the weld joint for smooth, firm, and efficient welding without welding powder.
Foot Switch Operation — Hands-free trigger keeps both hands free to hold and position the workpiece during welding.
Coarse and Fine Power Adjustment — Dual-knob adjustment for precise output control across different wire sizes and workpiece requirements.
0.5–1.5 mm Welding Range — Wider range than 30A and 50A models, suitable for ring mouths, melon buckles, and medium-gauge jewelry components.
Universal Voltage — Available in 110V and 220V for worldwide use.

Operation Steps
Connect the electrode clamp to the negative output pole and the electrode holder to the positive output pole. Turn on the power supply and power switch.
Adjust the power knob using coarse and fine adjustment to the required output level.
Use tweezers to clamp the workpiece and align the interface with the tungsten needle at approximately 5 mm distance. The workpiece must not contact the needle.
Step on the foot switch briefly to complete the spot weld. Release immediately after each weld.
Safety Notes
Do not hold the foot switch down continuously — step and release immediately. Prolonged contact will damage internal circuits.
Welding flash is harmful to eyes. Use appropriate eye protection during operation.
Do not touch the metal parts of the tungsten needle and tweezers simultaneously while the foot switch is engaged.
Do not disassemble the machine — high voltage is present internally.
