WP4 / WS4 Series
General Catalog of TIG Welding Machines
* In addition to this product (welding power source), a torch and gas regulator are required for welding.
Key functions
-
One unit serves seven purposes (WP) for applications to a wide range of welding conditions
-
Achieves high-quality welding through pulse welding (WP)
WP4 is the only model that supports AC manual welding. It also supports various other welding processes and can be applied to a wide range of welding conditions.
One unit serves seven purposes for applications to a wide range of welding conditions
One unit supports a wide range of welding processes. Switching between welding processes can be done with a single-touch operation. WP4 is equipped with pulse welding functions.
Achieves high-quality welding through pulse welding
The WP4 series is equipped with pulse welding functions. This welding process is effective for welding of thin plates, which tend to burn through, penetration welding, welding of aluminum, which has good thermal conductivity, and welding of aluminum alloy materials.
