HALDEN PTA Welding Solutions
Integrated Plasma Powder Welding Machine DML-V03BD
A compact and powerful PTA surfacing solution with high integration, DSP digital control, strong cooling capacity, and flexible powder feeding modes.
Product Overview
The DML-V03BD Integrated Plasma Powder Welding Machine is designed for PTA surfacing and repair welding applications that require compact layout, reliable digital control, and stable long-time operation.
This model integrates the plasma arc power supply, main power supply, refrigeration water tank, and powder feeding controller into one machine platform with programmed linkage control for convenient and flexible use.
Why This Machine Stands Out
Highly Integrated Design
The main arc power supply, dimensional arc power supply, powder feeding control system, and refrigeration system are integrated into one compact unit.
DSP Digital Processing
DSP digital processing technology provides high-speed response and precise control.
Stable Current Output
Digital inverter technology helps ensure stable current output and a wide adjustment range.
Reliable Arc Starting
High-voltage design supports smooth arc starting and helps ensure arc stiffness and arc length stability.
High-Power Cooling
A 5200 W refrigeration system supports long-time and high-load working conditions.
Flexible Powder Feeding
Supports automatic, manual, advanced, and delayed powder feeding modes to match different surfacing requirements.
