GR3 Series (YD-350GR3 / YD-500GR3)
GR3 Series Catalog
*In addition to this product (welding power source), a wire feeder, remote control unit, torch, and gas regulator are required for welding.
Key functions
-
Full digital control achieves high-quality welding
-
High-precision encoder feedback control
-
Enhanced mobility achieved by eliminating the remote control unit cable to the power source
-
Easy-to-use operation panel and remote control unit
-
An aluminum welding model is also available
Full digital control ensures stable output from the start to end of welding. Significantly reduces the amount of spatter compared to conventional inverter-type models.
The motor of the wire feeder was reviewed for improvements, enabling consistently uniform wire feeding.
Mutual compatibility of ancillary devices has been achieved with the VR series. The wire feeder and torch can be used without any modifications.
Achieves high-quality welding with a smooth and stable arc start
This series enables a quick current rise when starting arc ignition, and a uniform wire tip shape through FTT control when completing welding, thereby achieving a consistently stable arc start. This series supports welding over a wide current range from a low current region to the rated current.
High-precision encoder feedback control
A motor equipped with an encoder performs high-precision wire feeding. The uniform wire feeding performance is maintained even when external factors occur, including changes in the power supply voltage and ambient temperature.
Enhanced mobility achieved by eliminating the remote control unit cable to the power source
Reduced the number of cables for improving ease of maintenance. Since the remote control unit is connected to the wire feeder, the number of cables for connecting the welding power source and wire feeder was reduced to three (control cable, power cable, and gas hose).
Simple and easy-to-use operation panel
A simple operation panel was adopted for the welding power source in conformity with use environments. Users can adjust all welding-related settings at their fingertips. The operation panel is bright and easy to see even in the welding frontlines and allows smooth settings in order from left to right.
A remote control unit for simple memory reproduction is also available
The recorded welding conditions can be reproduced by the remote control unit. (5 conditions)
An aluminum welding model is also available
The 350GR3-based model is capable of hard aluminum welding.
