Welbach PROXUS 250P semi-automatic welding machine, 230V, 250 A

The Welbach semi-automatic welding machine is an excellent device for welding metal components. It is ideally suited for work in factories, workshops, production facilities, and construction sites. The PROXUS 250P model uses the MIG / MAG welding method designed for welding magnesium, copper, and other non-ferrous metals and their alloys. Excellent performance, modern technology, and precise adjustment will allow you to create clean and durable weld seams.

The semi-automatic machine features high efficiency, with a maximum welding current of 270A. The device is powered from a 230V network, so the semi-automatic machine can be used very widely. The PROXUS 250C is manufactured using IGBT technology, making it more efficient than most other devices. The semi-automatic machine is particularly safe and has compact dimensions. The PROXUS 250C features TIG Lift ignition, which offers many advantages:

• Avoidance of interference with electronic components (unlike high-frequency ignition)
• Precise setting of the welding start point is possible
• Simple and safe ignition
• No risk of tungsten inclusions
• No damage to the electrode tip
• Easy ignition when using long cables

2T/4T welding functions greatly facilitate work. 2T mode allows welding by pressing and holding the welding torch button. It is perfect for making spot welds. In turn, 4T is activated by a short button press. To finish, press the button again. This allows you to conveniently make long seams.

Synergic modes allow you to set only one parameter (e.g., power or material thickness), while the other parameters (wire feed speed or current) are adjusted automatically. In addition, the PULSE function configurations have been saved in the device computer to ensure the best working results.

Features and functions:

• Manufactured using IGBT technology, therefore it is resistant to short circuits. IGBT is a newer continuation of MOSFET technology. С
• The device is manufactured according to strict European standards and has been checked for compliance with CE and RoHS. This guarantees a long service life and high quality.
• At the back of each device there is a bolt marked with the grounding symbol. Before starting work, it must be grounded with a wire whose cross-section must be at least 6 mm².
• MMA welding capability
• The PULSE function allows reducing the amount of heat delivered to the material. Ideal for welding thin metal sheets. In the case of MIG welding, it is excellent for aluminium processing.
• 2T/4T welding modes
• The 2T function means starting work by pressing the button on the torch and stopping by releasing the torch button.
• During the 4T function, pressing the button on the torch opens the solenoid valve, gas pre-flow occurs, and the electric arc ignites. After ignition, the current equals the start current. When the button is released, the output current value increases to the welding current value. The welding process is stopped by pressing the button on the handle again.
• Powered from a single-phase network (230 V +/- 10 %).
• The Hot Start function facilitates arc ignition by temporarily increasing the welding current when the arc ignites. After ignition, the welding current returns to the set value.
• The Anti Stick function prevents the electrode from overheating when it sticks to the material, as the current is automatically reduced.
• LED display
