400A PTA Welding Machine
Establishing a welding pool on the working piece by the plasma arc, and then filling in the hard-facing powder on the surface, to make the working piece well corrosion & wear resistance. This is suitable for extrusion screws, ball valves, butterfly valves, drilling tools, valve seats, glass mold, boils... etc.
Features |
-
Sturctured by IGBT Chopper, for the most efficient and stable output current.
-
Controlled by a touch screen.
-
Comes with independent gas flow meters for plasma gas, shielding gas, and carry gas.
-
Digital control for output current, RPM of powder feeder, gas pre-flow & post-flow time... etc.
-
Parameters could be saved in the machine, and restored agin for the same welidng quality in the future.
-
Initial, welding, crater, and pulse current all could be set respectively for the best welding outcome.
-
Torch tip is directly water cooled, which is designed for high duty-cycle usage.
-
Powder feeder is driven by servo motor. The powder feeding rate could be mirco and precise adjustable.
-
The hopper of powder feeder is transparent. It is easy to see the amount of remaining powder in the feeder.
-
The control of automation and PTA welding could be combined in a single touch screen for change and monitoring
