Migatronic FLEX2 3000 Compact Manual De Instrucciones página 21

Connection of shielding gas
The shielding gas hose is fitted to the back panel of
the power source (3) and is connected to a gas supply
with a pressure reduction to 2-6 bar. 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.
