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 – Function HOT START is designed for easier arc ignition.
ARC FORCE – Function ARC FORCE is the prevention against the unwanted
sticking of the electrode to the weldment and against the unwanted arc
extinguishing.
ARC FORCE is off – 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 PEGAS 400 E CEL generate the open-circuit voltage
95 V (MMA) and 14 V (TIG) and inverters PEGAS 500 E generate the open-
circuit voltage 90 V, 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.
