Sincro SW-F Series – 2-Pole DC Welders/Generators with SCR Technology
The Sincro SW-F Series is a range of Made in Italy 2-pole direct-current welders/generators, specifically developed for SMAW (Shielded Metal Arc Welding) and on-site applications. Built on advanced SCR electronic technology, the SW-F units combine 4 essential functions into a single compact and reliable solution:
4-in-1 Functions:
DC Welder – 300A output, with electronic SCR regulation for excellent arc stability and precision
AC Generator – single-phase and three-phase outputs for auxiliary power on-site
Battery Charger – with reverse polarity protection for safe charging
Jump Starter – for emergency starts, even in remote or inaccessible areas
Key Features:
Electronic SCR regulation – ensures stability and precision of the welding current
Supports all electrode types – rutile, basic, and cellulosic
Additional welding aids included: Hot Start, Arc Force, and Anti-Stick
Remote control availability – polycarbonate front panel designed for remote use
Thermal overload protection – automatic reset included
Alternator type: Brushes | IP23 protection class
