Productdetails

SMC® (Smart Machine Control) - intelligent higher-level machine control concept for excellent welding results and simple, safe operation
SDI® (Stepless Dynamic Induction) - stepless, electronic welding choke with ultra-fast control for excellent ignition characteristics and a stable arc
RSC® (Realtime Speed Control) - real-time monitoring and precise control of wire feed speed to prevent seizing
Powerful four-roll precision feed system with tool-less roll changing
CCM (Characteristic Curve Memory) - integrated welding parameter database with stored characteristic curves provides the appropriate welding parameters for all tasks
RMI (REHM Machine Interface) - for fast and safe setting of welding parameters with simultaneous easy handling
Weldable materials: Fe, Al, CuSi3, CrNi
Burn-in stabiliser detects changes in the stick-out (free wire end) and automatically corrects the arc power - uniform burn-in in any position
Mains voltage compensation - automatic detection of fluctuations in the mains voltage and automatic adjustment of the wire feed according to the mains voltage
Automatic creep-in controls the wire feed speed until the arc is safely ignited, creep-in speed can also be changed manually if required.
SYNERGIC.PRO 251-4 QUATTRO-MIG is particularly suitable for use in thin sheet processing from 15 A welding current due to special synergy programs and SDI technology.
In the models of the industrial series SYNERGIC.PRO 304-4 / 404-4 / 504-4 focused arc can be activated at the touch of a button: higher deposition rate than spray arc, welding with short and powerful arc, safe root detection, safe flank detection and reduced penetration notches
Units easily manoeuvrable and transportable in the workshop and on site due to robust chassis with large, easy-running wheels
Pleasant, low-noise continuous operation due to optimum housing design and standby switching of fan and water pump
Optionally available with centrifugal pump
Three years REHM guarantee

Focussed arc: welding process FOCUS. ARC can be activated for higher deposition rate, short pressure-filled arc, safe root and flank detection and reduced stickout
Mains voltage compensation: The arc automatically adapts to the input voltage
Stickout stabiliser: Changes in the stickout are compensated by this control feature
All units with slanted downward 4-roller drive for optimum wire feed
Optimised characteristics for even better arc when welding Fe, Al, CuSi3 and CrNi
Optionally available with centrifugal pump
