INTRODUCTION
The Discovery 161MF is a compact and heavy duty generator for
MIG/MAG welding.
The reduced weight and compact size allow it to be carried wherever
it is needed: it is designed to give you maximum power, reliability and
efficiency.
Wire reels of up to 200 mm in diameter can be mounted.
Sound alarm. A sound alarm has been provided to protect the power
generator: it blocks the primary inverter in the event that the average
welding current should exceed 160 A for more than 0.6 seconds.
Accessories that can be connected to the unit:
-Overcut device to protect the power source from power supply
voltage spikes that could damage the electrical components.
-Power source trolley.
-Spool gun torch.
The DISCOVERY 161MF power generators can be supplied together
with the 6 meters MIG SPOOL GUN torch with 1 kg D100 wire spools;
in the MIG welding mode they are able to weld SG2 solid wires, 0.6-
0.8 mm stainless steel wires, 0.6-0.8-1.0 mm aluminum wires and 0.9-
1.0 mm cored wires with or without gas shielding.
The SPOOL GUN torch features:
-A wire drawing motor with two rollers, one above the other, on the
torch.
-A spool support reel for 1 kg D100 wire spools.
-A 6 meters long torch.
Consult your dealer for an updated list of accessories and the latest
available new products.

MEANING
EVENT
CHECKS
Overheating alarm
Indicates tripping of the welding power source
thermal protection.
All functions disabled.
Exceptions:
-cooling fan.
Leave the unit running so that the overheated
components cool as rapidly as possible.
When the unit has cooled, the welding power
source will reset automatically.
-Make sure that the power required by the
welding process is lower than the maximum
rated power output.
-Check that the operating conditions are in
compliance with the welding power source
data plate specifications.
-Check for the presence of adequate air
circulation around the welding power source.
Overcurrent alarm
Indicates tripping of the welding power source
current surge protection.
All functions disabled.
Exceptions:
-cooling fan.
An audible signal will sound (buzzer).
Muting the audible signal:
-in torch trigger procedure 2T, release the
torch trigger.
-in torch trigger procedure 4T the alarm
mutes automatically after 5 seconds.
Exit the alarm state by performing one of the
following actions:
-press any button.
-switch the power source off.
-Check that the programmed arc voltage
value is not too high in relation to the
thickness of the work to be welded.

WELDING CURRENT
Output current value during welding.
POST GAS TIME
Time of post gas delivery when the welding arc is extinguished.
This is useful when welding at high current values or with materials
that oxidise readily to cool the weld pool in an uncontaminated
atmosphere.
In the absence of specific requirements the value should generally be
kept low.
Consequences of a higher value:
-More effective pickling (improved appearance of workpiece at the
end of the welding pass).
-Higher gas consumption.
Consequences of a lower value:
-Lower gas consumption.
-Oxidation of electrode tip (more difficult arc strike).
MIG/MAG WELDING VOLTAGE
The parameter sets the welding voltage in MIG/MAG mode.
WIRE FEED RATE
The parameter sets the output wire feed rate.
