Use of simulator control method allows stable arc and constant voltage characteristic in the entire welding current range consistently from the minimum to the maximum current.

 Power reduction circuit that automatically operates by toggle switch operation makes it possible to reduce unnecessary no-load power even while there is no arc.

 Soft arc, which minimizes damages to the base metal and the welded material caused by spatters, generates and optimizes the welding condition. Consequently it tributes to enhancing work efficiency and improving product quality.

 Each function is implemented on a separate printed circuit board, allowing prompt and accurate repair upon function failure.

 Fixed-speed wire feeding and excellent controllability ensure reliable fusing speed and efficiency.

 The main transformer reactors and radiating fins have been designed to meet the safety specifications in consideration to the temperature characteristic value and the insulation, which extends the life time of switching elements and the power converter part.

 Work process and design are standardized in consideration to safety and durability in writing and part handling.
