Description:
SPARTUS® ProARC 500 CEL is a modern inverter welding machine based on IGBT transistors. The power supply is from a 400V three-phase network. It allows welding with electrodes wrapped in a wide range of diameters, with a maximum current of 500A.
The welder is resistant to very heavy loads, has an efficient cooling system and a high 60% rated duty cycle, and 100% duty cycle achieves for an intensity of 400A.
The device has a number of modern technological solutions:
•MCU controller
•Protection against phase loss,
•VRD - reduced voltage without load
Thanks to the ProARC500 solutions, CEL has stable output parameters and functions that guarantee high quality of the welded joint:
•Adjustable Hot Start function - easier ignition of the coated electrode
•Adjustable Arc Force function - easier welding in difficult positions such as ceiling
•Anti-stick function - prevents sticking of the electrode
•Support for cellulose electrodes - the possibility of welding with cellulose electrodes
•the possibility of TIG welding with striking the Lift arc (by rubbing)
SPARTUS® ProARC 500 works well in professional welding work, where high power and reliability of the source is required.
Example application: industry, constructions, renovation works in the field, workshop works.
