Migatronic FLEX 2 3000 Compact Manuel D'instruction page 18

Important: stretch out welding hose, earth cable
and interconnecting cable, as necessary, as shown
in the figure to avoid affecting the welding
performance and at worst destructing the welding
machine.
Lift instructions
The lifting points must be used
(please see figure) when lifting the
machine.
The machine must not be lifted
with mounted gas bottle.
Do not lift the machine by the
handle.
Do not step on the handle
Connection of shielding gas
Connect the gas hose, which branches off from the
back panel of the welding machine (3), to a gas
supply with pressure regulator (2-6 bar).
(Note: Some types of pressure regulators require an
output pressure of more than 2 bar to function
optimally).
One/two gas cylinders can be mounted on the bottle
carrier on the back of the trolley.
Connection of torch for MIG/MAG welding
The welding hose assembly is pushed into the
central connector coupling (4) and the nut (5) is
tightened by hand. If a water-cooled torch is used,
the cooling hose is connected to the blue quick-
release fitting (7) and the return hose to the red
quick-release fitting (6). The return lead is
connected to the negative pole (8).
Moreover, a multi-plug must be connected on the
front of the machine (9) if the torch is a MIG
Manager ® .
Note: MIG Manager ® can only be connected if a
connection kit is mounted in the machine (special
equipment).
Connection of electrode holder for MMA
The electrode holder and return current cable are
connected to plus connection (10) and minus
connection (8). Observe the instructions from the
electrode supplier when selecting polarity.
Control of cooling liquid
If the machine is delivered with an integrated torch
cooling module, it will be necessary to inspect the
cooling liquid level by means of the level control (11).
Refillment of cooling liquid takes place through the filler
neck (12).
Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently quickly when welding stops. The required
brake force is dependent on the weight of the wire reel
and the maximum wire feed speed. A brake torque of
1.5-2.0 Nm will be satisfactory for most applications.
Adjustment:
- Dismount the control knob
by placing a thin screw
driver behind the knob
and thereafter pull it out
- Adjust the wire brake by
fastening or loosening the
self-locking nut on the
axle of the wire hub
- Remount the knob by
pressing it back into the
groove.
Trolley with automatic mains voltage transition
(Special equipment)
Machines supplied with autotransformer can be
connected to the following mains supplies:
3*230V, 3*400V, 3*440V og 3*500V.
Press the power switch (13) to turn on the
autotransformer (green indicator light). The built-in
energy saver function will automatically turn off the
welding machine after 40 minutes of inactivity. Press the
button (14) to turn on the machine again (red indicator
light).
The energy saver function can be permanently
disconnected by a Migatronic technician.
