This Stationary Spot Welding Machine is a micro-computer controlled system designed for automated projection and spot welding applications, with a common use in fabricating components like automotive fuel tanks. Operating on a 380V/50Hz three-phase AC power supply, it utilizes three-phase rectifier and inverter technology along with a feedback control system to manage the welding heat cycle. This includes control over pre-press, weld, hold, and off times to meet specific welding requirements. The machine offers multi-process capability for materials such as low-carbon steel, stainless steel, and non-ferrous metals.

A. Controlled & Versatile Welding Process

• Programmable Welding Cycles: Micro-computer control allows for precise management of the welding sequence, including pre-press, weld, hold, and off times, aiming to accommodate different material and thickness requirements.

• Multi-Material Application: The system is designed to weld a range of materials including low-carbon steel, stainless steel, coated steel, and non-ferrous metals in forms such as wire, sheet, and pipe.

B. Robust Power & Stable Construction

• Dedicated Resistance Welding Transformer: Equipped with a specialized transformer featuring forced internal water-cooling and high-grade silicon steel, designed for strong power output and a high-duty cycle in industrial environments.

• Stable Pressure Application: The machine structure incorporates upper and lower electrodes with an auxiliary stroke pressure mode, intended to provide stable application of force during welding.

C. Adaptive & User-Friendly Operation

• Multiple Program Storage: The micro-computer controller can store up to 16 sets of welding parameters, facilitating quick changeover for different production jobs or material types.

• Broad Industry Application: Engineered for use in various industries such as automotive, appliances, and hardware for projection welding processes on components like nuts, studs, and brackets.
