DURWELD PTA welding systems
The mobile welding systems DURWELD 250T-M PTA, DURWELD 300T-M PTA, DURWELD 400T-M PTA and DURWELD 800T-M PTA were developed as economical and powerful welding units for manual and automated PTA buildup welding.
The welding systems are equipped with state-of-the-art performance components, including a PLC and a 3.9 kW heat exchanger. The process gases are controlled by low-cost manual gas flow controllers (DURWELD 250T-M PTA) or precise electronic mass flow controllers (DURWELD 300T-M PTA, DURWELD 400T-M PTA, 800T-M PTA). The main inverter power sources used are primary cycled. These produce a stable arc that ensures consistent and reproducible coatings. The welding units are available in various versions with different equipment features at extra cost. Optionally also available as control cabinet version.
Features:
- Active air cooling of the power sources
- Built-in cooling unit
- Modular plant design
- Excellent price-performance ratio
- Mobile control unit
- Modern PLC technology
