• MMA
- Option to choose between the MMA DC and MMA AC electrode welding.
-
The VRD (Voltage Reduction Device) can be activated, which reduces voltages to below 12 V, which means
that the welding machine can be used in ambient conditions in which there is a high electrical risk, thereby
providing maximum operator safety.
- “Arc Force” adjustable to select the best dynamic characteristics for the welding arc.
- “Hot Start” adjustable to improve ignition with particularly difficult electrodes.
- Anti-sticking function to avoid the electrodes sticking.
MATRIX X220 AC/DC
The PFC device makes the wave form of the current absorbed sinusoidal, which results in no harmonic disturbance on the mains and
optimisation of absorption, which allows you to use the generator’s full power with a 16 A fuse, as well as ensuring greater protection of
the welding machine against fluctuations in the power supply voltage.
Usage limits (IEC 60974-1)
The use of a welder is typically discontinuous, in that it is made up of effective work periods (welding) and rest periods (for the positio-
ning of parts, the replacement of wire and underflushing operations etc.
This welder is dimensioned to supply a I
2
max nominal current in complete safety for a period of work of X% of the total usage time. The
regulations in force establish the total usage time to be 10 minutes.
The work cycle is considered to be X% of this period of time. If the permitted work cycle time is exceeded, an overheat cut-off occurs to
protect the components around the welder from dangerous overheating.
Tripping of the trip switch is indicated by the
symbol on the display (see the manual for the XVision control panel).
After several minutes the overheat cut-off rearms automatically and the welder is ready for use again.
