1. INTRODUCTION
Dear consumer,
ompany ALFA IN a.s. thanks you for buying our product and believe that you
will be satisfied with our machine.
Welding inverters PERUN 160 E – 220 E are designed for professional welding
in MMA method (coated electrode) and in TIG method with touch ignition
(LIFT AR ).
Welding machines are equipped with ecological function FOD – fan on demand.
This function ensures that after about 4 minutes of inactivity, the electronics will
turn off the fan, then the electronics will turn on the fan automatically, when you
start welding again. This leads to less wear, less noise and power saving.
ontent of functional equipment is also switchable function VRD to protect the
welder against the unpleasant effects of open-circuit voltage, adjustable function
HOT START for perfect arc ignition, adjustable function AR -FOR E which
ensures stable arc and function ANTI STI K which prevents the electrode
sticking to the weldment.
Welding machine may be operated only by trained persons and only in the
technical provisions. ompany ALFA IN a.s. accept no responsibility for damage
caused by improper use. Before commissioning please read carefully this

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 AR FOR E is the prevention
against the unwanted sticking of the electrode to the weldment and against the
unwanted arc extinguishing.
Decreased AR FOR E – it is used at medium and higher welding currents.
Maximal AR FOR E - it is used if you weld with low currents (vertically up, over
the head, etc.).
Increased AR FOR E – it is used for easier arc ignition and arc maintaining,
for good penetration.
When welding thin sheets, AR FOR E 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.
