Mini TIG Spot Welder – Stainless Steel Cold Welding Machine

Add precise pulse control to a compatible argon arc TIG welder with this compact SL-MINI controller. It is designed for controlled single-point and continuous welding work, with adjustable welding time, interval time, pulse frequency and duty ratio, and memory for up to 20 setting groups, so repeat work can be set up more consistently.

• Precision pulse control for argon arc TIG welding, including single-point and continuous modes
• Adjustable welding time, interval time, pulse frequency and duty ratio
• Memory for up to 20 setting groups
• Compact controller for a workshop bench, sized 125 x 80 x 70 mm as listed
• Set A and Set B options as listed

Important: this is a controller, not a complete welding machine. It cannot be used alone. It must be connected to a compatible argon arc welding machine. The supplier lists it as compatible with most high-frequency arc ignition TIG welders, but compatibility, connectors and package contents for the selected set must be confirmed before ordering.

Specifications as listed by the supplier: Product name: argon arc welding precision pulse controller; model SL-MINI; applicable models listed as Single-Use, Dual-Use and Three-Use argon arc welding machines; working modes listed as Single Point, Continuous, Argon Arc Welding, 2T and 4T; power consumption 1 W; memory preservation 20 groups; input voltage DC 9 V, 1 A; product size 125 x 80 x 70 mm; output signal 3-48 V; net weight 410 g; welding time 1-999 ms; interval time 1-999 ms; pulse frequency 1-20 Hz; pulse duty ratio 1-99%.

Setup notes as listed: Set the welder's original current to approximately 200 A, or maximum, enable only the welding current and argon gas delay functions on the welder, and disable other functions. Adjust the controller's welding time from the listed starting value of 80 if the arc strength is insufficient or too strong. Do not use the welder's built-in argon welding mode after connecting the controller.

Please confirm before ordering: Whether the selected set includes the controller, cables, foot pedal and any other accessories shown, the exact welder models and connectors it fits, and whether an adapter or separate power supply is required. Specifications not listed are not guaranteed. The supplier also states that this product is not suitable for buyers expecting welding without discoloration, without polishing, without deformation, without temperature after welding, or without argon gas, so check suitability for the intended work first. Welding is skilled work: use appropriate training, protective gear, grounding, ventilation and fire precautions, and follow the manufacturer's operating instructions.
