Amada Miyachi America Inc. announced that the MAWA-300A pulsed micro TIG welder has a touch start feature that controls and identifies weld location. The new feature is for welding delicate parts where it is important to start with a low voltage. 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.
