Low Spatter Control

This is our proprietary electronic reactor born during the development of our V series full-digital welding machines. They achieve high-speed control of welding current waveforms. Full software control makes welding pleasant over the entire current range, from low to high current, and greatly reduces the amount of spatter.

MTS control (MTS-CO₂)

MTS control is an abbreviation for Metal Transfer Stabilization Control. It opens the short circuit and reduces the vibration of the molten pool when the arc is rearced. It also suppresses micro-shorts during the arc period.

The first difference between the conventional CO₂ method and MTS-CO₂ droplet transfer is the initial short　circuit. Short circuits are detected with high accuracy, and secondary switching^*1 sharply reduces the current to prevent micro short circuiting (spatter generation), and then transitions to a reliable short circuit. (Initial short circuit control)

Wire tip nicks are also detected and the current is rapidly reduced by secondary switching to prevent the fuse effect (spatter generation) at the wire tip. (Neck control)

*1: Secondary switching is a control method to reduce spatter by dropping the welding current sharply immediately before and after a short circuit to smoothly transition to a short circuit or arc.
