STAHLWERK AC/DC TIG 315 Puls Pro Fully Equipped Welding Machine – water-cooled 315 A industrial welding machine with 1.6 kW water cooling, AC/DC pulse, MMA/manual arc, spot, HF, and lift TIG ignition, digital display, 400 V

The STAHLWERK AC/DC WIG 315 Puls Pro, fully equipped with a 3-in-1 automatic welding helmet and all necessary accessories and consumables is a water-cooled TIG inverter welder for professional applications with both direct and alternating current. It delivers 5–315 A in TIG mode and 30–270 A for MMA/electrode welding and is suitable for industrial, metal fabrication, workshop, and trade applications. The unit supports DC TIG, AC TIG, DC and AC TIG pulse welding, as well as MMA/manual arc welding. AC mode enables welding of aluminum and aluminum alloys. AC frequency, AC balance, and cleaning current can be precisely adjusted to the material, oxide layer, and desired bead shape. Rectangular, triangular, trapezoidal, and sinusoidal waveforms are available for AC operation. In pulse welding, the pulse current, base current, pulse width, and pulse frequency can be individually adjusted. This allows for control of heat input and reduces the risk of burn-through or distortion. The digital control panel and central rotary knob allow for convenient adjustment of gas pre-flow, hot start, start current, current rise, welding current, current reduction, final current, and gas post-flow. Ten memory slots allow you to save frequently used parameters. In addition to 2T and 4T operation, the unit offers spot and repeat welding functions in spot mode. The welding current can be controlled using a suitable foot pedal via the three-pin remote control connector. The CT-500 cooling system is controlled directly by the welding machine. With a cooling capacity of 1.6 kW, a tank volume of 5 liters, and a flow rate of up to 8 l/min, it ensures reliable cooling of the torch and hose assembly. An integrated flow monitor alerts the operator to malfunctions in the coolant circuit via the display. Modern IGBT technology and pulse width modulation (PWM) ensure efficient and stable welding performance. Hot Start and Anti-Stick features support MMA welding. The rugged ST-Guard housing, powerful fan cooling, and transport cart with gas cylinder holder, cable holder, and storage surface enable reliable professional use in industrial settings or for demanding metal fabrication work. The fully equipped STAHLWERK AC/DC WIG 315 Puls Pro comes with a comprehensive accessory package designed to meet the highest demands.
