Overheating of the machine –
LED ALARM lights up and the machine switches
to the mode, when is effectively cooled to the operating temperature. Don’t use
the machine for about 15 minutes. Until the machine reaches the operating
temperature, it remains in „cooling mode“ and the machine will only be able to
supply reduced welding current.
HOT START
– range 1 – 10, default 5, Function HOT START is designed for
easier arc ignition.
ARC FORCE
– range 1 – 10, default 3, Function ARC FORCE is the prevention
against the unwanted sticking of the electrode to the weldment and against the
unwanted arc extinguishing.
Decreased ARC FORCE – it is used at medium and higher welding currents.
Maximal ARC FORCE - it is used if you weld with low currents (vertically up, over
the head, etc.).
Increased ARC FORCE – it is used for easier arc ignition and arc maintaining,
for good penetration.
When welding thin sheets, ARC FORCE increases the risk of burning.
MMA VRD
– Voltage Reduction Device. If this mode is active and when
the welding process is finished, the VRD immediately reduces the open-circuit
voltage to 14 V. Inverters PERUN 160 E – 220 E generate the open-circuit
voltage 70 V (MMA) and 70 V (TIG), which is safe and is in compliance with the
standard EN 60974-1. However, in a certain environment the welder can feel
very unpleasant tingling – electrical shocks. If the MMA VRD mode is active, it
will not exposure the welders to those unpleasant states. If the VRD function is
not turned on, the control will reduce the open-circuit voltage to 14 V after 90 s.
