Machine for argon arc Welding on Alternating and direct Current

URAL-TIG 550 is designed: for argon-arc welding with direct and alternating current or in pulse mode with contact and contactless ignition of the arc of alloyed and non-ferrous metals, thin sheet metal; for manual arc welding with direct and alternating current or in pulse mode with a pulsating arc. Adapted: for operation from generator sets of mobile workshops; for installation work during repair and construction of pipeline piping, compressor stations; for work in shipbuilding; for the production of building structures, process tanks. Ensures: stable operation with fluctuations in the voltage of the power supply network (+ 15 / - 15%); operation at temperature differences from -200C to + 400C.; easy adjustment of welding parameters due to the LCD display and digital indication of the welding current and voltage values; equipped with a liquid cooling unit for the torch; convenient movement due to the installed wheels and a platform for the cylinder; can be equipped with a remote control or a pedal. Features of the welding machine: the machine boards are reliably protected from dust and moisture; protection of power modules from overheating, increased voltage of the external network and long short circuit; the presence of ventilation ducts and an intelligent fan mode reduce contamination of the welding inverter; self-diagnostics and diagnostics of the external network with fault indication; saving of RD and RAD welding modes 100 memory cells; after the end of welding, a five-second indication on the display of the last current and voltage settings; the ability to change the welding current adjustment range from the remote control; connection of a remote control with digital indication. Functions in the RD welding mode: protection against electrode sticking; "hot" start (start current and start duration are adjusted), forcing the short-circuit current; pulse mode when welding with direct or alternating current; limiting the open circuit voltage to a safe 12V; Functions in the RAD welding mode: synergistic or manual setting of welding modes; With synergic setting, the welder sets the name of the metal, its thickness and spatial position of the weld; torch trigger operating modes: 2T, 4T, 4T2 (two-level current) and spot welding; adjustable parameters: pre-weld gas time, start current, start time, current rise time, welding current (pulse current), pulse mode pause current, pulse filling, pulse frequency, current fall time, crater current, crater current time, post-weld gas time; for alternating current: frequency, balance, current shape (sine wave, rectangle, trapezoid, triangle), mixed current (alternating alternating and direct current). Selection of electrode sticking protection modes, gas test mode.
