Single Phase AC Spot / Projection Welder
Single Phase AC Spot / Projection Welder
The Single Phase AC Spot / Projection Welder is a compact and efficient machine designed for joining metal sheets and components through resistance welding. Using alternating current (AC) and precise electrode pressure, it creates strong, clean, and repeatable welds suitable for both light and medium-duty fabrication tasks.
This welder is widely used in automotive, electrical, appliance, and sheet metal industries, offering a perfect balance of performance, reliability, and cost-effectiveness. With its rugged frame, high-efficiency transformer, and stable current control, the machine delivers consistent weld quality while minimizing power consumption and maintenance requirements.
Key Features
- Upside insulation is convenient for other device installation. Lowerside accident like short circuit when installing welding jigs can be prevented.
- Epoxy-resin filled transformer ensured the welding quality and reliability.
- Water flow display is installed easy for checking the cooling water condition.
- Vertical type pressure mechanism has the advantage such as high speed, reduced the gas consumable, good following performance, low noise and long life.
- Pressure head up and down speed can be adjusted continuously. It reduced the pressure impact to the work piece and reduced noise also.
- Fast and convenient to switch the double shock of the pressure mechanism.
