Welding machine Specialist-250
Professional welding machine Specialist - 250 has PN = 100% at maximum current and work with an electrode of Ф5 mm.
Designed for manual arc welding with covered electrodes with an unstable and weak power supply. Equipped with Anti - Stick function, which cuts off the current when the electrode sticks. Has protection against overvoltage of the mains over 265V and undervoltage less than 150V. Adjustable arc afterburner. Digital indicator. Welding inverter Specialist - 250 is recommended for serious work when a continuous process is required, electrode by electrode, 4 and 5 mm in diameter and there is no time for cooling due to equipment overheating. The device is equipped with a powerful cooling fan and cables 25 mm sq. Due to the appropriate transformation ratio of the pulse power transformer, the voltage amplitude in the output pulse is 110 volts, therefore arc ignition, even at the lowest welding current value, is very easy, with all types of electrodes, the arc is very stable, and the seam lays down even, beautiful and without defects. To reduce the likelihood of an electrical breakdown when dust and dirt gets inside the device, the printed circuit boards are covered with a compound "Viksint PK - 68".
Delivery set: apparatus, welding cables KG - 1 - 25 copper, length 2m + 2.5m with mating connectors 35 - 50 (350A), electrode holder 500A and clamp of weight 500A, carrying belt, passport, packing box.
