Features and Advantages of this Askaynak MMA Welding Machine 251 ultra

  • Digital inverter technology.

  • Excellent arc characteristics and outstanding performance for rutil and basic electrode types.

  • Ideal for welding of carbon and low-alloy steels, even stainless steels.

  • 380V-3Ph input voltage and maximum output current of 250 A provide a continuous welding operation with electrodes in diameters of 2.5, 3.2 and 4.0 mm.

  • Hot-Start feature allowing the welder to increase the welding current at the start of the electrode.

  • Arc-Force to prevent freezing the electrode in the welding puddle.

  • Suitable for operation on site or within a workshop environment by providing maximum flexibility.

  • 21.5 kg weight.

  • Digital ampermeter.

  • Fan cooling.

  • Thermostatic overload protection and indicator light.

  • Easy-to-use and user-friendly control panel.

  • Recessed controls and connections designed to help protect controls from damage.

  • Two quarter-turn (positive and negative) output terminals for easy cable connection.

  • IP21S protection class.

  • Meet EN60974-1 and CE standards for safety and reliability.

  • Two years warranty on parts and labor.

Arc-force Hot Start Features as Advantage

Arc-Force gives a power source variable additional amperage during low voltage (short-arc-length) conditions while welding. Helps avoid "sticking" stick electrodes when a short arc length is used.
Hot-Start used on Inverter 251-Ultra makes it easier to start difficult-to-start electrodes and used for arc starting only.

Frequently Asked Questions
1. Can I weld different types of metals with the same welding machine?

It depends on the type of welding machine. Some machines, like MIG and TIG welders, are versatile and can weld a variety of metals, including steel, stainless steel, and aluminium. However, it's important to ensure that the machine and welding process are suitable for the specific metal you intend to weld.

2. How do I determine the correct welding parameters?

The correct welding parameters, such as amperage, voltage, wire feed speed, or tungsten type, depend on factors like the type and thickness of the metal, the welding process, and the desired weld quality. Welding procedure specifications (WPS) or welding guidelines provided by the manufacturer can help determine the appropriate parameters.

3. Can I weld without using a welding machine?

Welding typically requires a welding machine to generate the necessary heat and electrical power. However, certain specialised techniques, such as forge welding or oxy-fuel welding, do not require a welding machine but have limitations and are less common in modern welding applications.
