Pulsed Micro TIG Welder Durable and reliable – this high performance micro TIG welding power supply is the perfect solution for welding coils and terminals, bus bars, and covered wires. Supplying between 30 and 300 amps of output power, this unit targets small components in the automotive, medical, battery, and electronics industry. Unique Touch Start and Pulsation features offer a higher level of control as compared to competitive models, providing more consistent and reliable welds. Amada Miyachi also supplies a full range of welding accessories for the MAWA-300A micro TIG welder, including torches, electrodes, torch stands, and safety helmets and gloves. KEY FEATURES • Capable of welding of conductive metals TYPICAL APPLICATIONS • Pulsation feature significantly reduces porosity • Touch Start feature controls and identifies weld location • Monitoring function checks the upper and lower limits of the current as well as the envelope of the waveform and identifies process errors. • Capable of welding of dissimilar materials • Digital programming interface facilitates easy pulse form control • Supports multiple weld schedules

• Controlled heat input to the part DOWN SLOPE DOWN SLOPE Pulsation allows the user to selectively turn the current on and off during the weld. The frequency can be up to 5 kHz for very rapid firing. Pulsation results in: • Elimination of internal porosity and external dimples pulsa t io n • Uniform size and shape of welds TOUCH START Touch Start drives the electrode to contact the workpiece and then retract at a given speed. The electrode starts firing in low current at a short distance from the part, controlling the location of the weld, and reducing the electrical noise emitted in the...
