Amada Miyachi announces that the MAWA-300A Pulsed Micro TIG Welder, now features a unique touch start feature that controls and identifies weld location. MAWA-300A is the perfect solution for welding small coils and terminals, bus bars, and covered wires as found in the automotive, medical, battery and electronics industries. MAWA-300A also has a pulsation feature that significantly reduces porosity. The updated welder features a higher level of control than competitive models, providing more consistent and reliable welds.

Durable and reliable, the high performance MAWA-300A micro TIG welding power supply features between 30 and 300 amps of output power, and can weld conductive metals and dissimilar materials. It features a monitoring function that can readily identify process errors by checking the upper and lower limits of the current as well as the waveform envelope. A digital programming interface facilitates easy pulse form control, and the unit supports multiple weld schedules.

The new touch start feature is specifically designed for welding extremely delicate parts, where it is important to start with a low voltage rather than a high voltage that can damage the parts. With touch start, the tungsten electrode is lowered until it just touches the workpiece. The electrode then retracts and a low voltage arc is fired. The torch further retracts to the welding position and fires as scheduled. With the touch start feature, the arc’s position is better defined and a lower start arc is required to generate the arc.

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.
