Equipped with voltage feedback control. This series significantly reduces spatter generated during MTS-CO2 welding and SP-MAG welding.
Equipped with HD-Pulse functions.
The HD-Pulse functions suppress undercut during high-speed welding while maintaining the quality of low spatter welding.
Low-spatter welding achieved by the MTS-CO2 welding method
This method suppresses the vibration of the molten pool when the reignition of the arc takes place after the short circuit is opened. In addition, it suppresses micro short-circuits that occur during the arc period, thereby reducing the amount of spatter by up to 70 %.
MTS : Metal Transfer Stabilization Control
Low-spatter and high-quality achieved by the SP-MAG welding method
The current is superimposed immediately after short circuit opening to increase the melting rate of the wire tip, thereby making the next short-circuiting smoother and shortening the cycle. This reduces the amount of spatter by up to 85 %.
The HD-Pulse welding method achieves reduced heat input and low spatter welding
HD-Pulse welding can achieve a shorter arc length and narrower molten pool compared to conventional pulse MAG welding, thereby achieving higher-speed welding. Furthermore, undercut is suppressed and gap tolerance is improved. It is ideal for high-current high-speed welding of medium thickness plates.
Easy-to-understand display for intuitive operation
Users can adjust all welding-related settings at their fingertips.
