3. INSTALLATION
This must be carried out by skilled personnel. All
connections must be carried out according to current
regulations, and in full observance of safety laws (CEI
reglement 26-10 – CENELEC HD 427).
- Make sure that the supply voltage matches the
voltage indicated on the specifications plate.
- When mounting a plug, make sure it has an
adequete capacity, and that the yellow/green
conductor of the power supply cable is connected to
the earth pin.
WARNING! Extension cords of up to 30 m must have a
crosssection of at least 2.5 mm².
3.1 DESCRIPTION OF THE EQUIPMENT
1) MIG Welding Torch Adapter (Euro connector).
2) Earth cable output terminal (-)
3) Shielding Gas Inlet.
4) Power switch: control power through and break
5) Power Access client: access to cable
6) Fan: for cooling the machine.
7) Digital display (Voltage).
8) Digital display (Welding current, Wire speed).
9) Indicates that the display
(8)
shows the MIG
welding wire speed.
10) Indicates that the display (8) shows the welding
current.
11) Power indicator: Indicates that the machine is
turned on.
12) The indicator will illuminate if the duty cycle of the
power source has been exceeded.
13) Switch for wire feed and Gas Test.
14) Wave control: Is used to adjust the intensity of the
welding arc.
15) Setting knob: In relation to the selected LED,
regulates: the welding current
(LED 10) or wire speed in MIG welding (LED 9) .
16) Setting knob: regulates welding voltage.
3.2 REEL FITTING SEQUENCE
1. Mount the wire reel.
2. The wire reel hub incorporates a friction brake which
is adjusted during manufacture for optimum breaking.
If it is considered necessary, adjustment can be made
by turning the large nut inside the open end of the
hub clockwise to tighten the brake.
3. Use the nut to secure the wire reel.
3.3 WIRE FEED
Make sure that the groove of the rollers matches the
wire diameter used. Mount the wire coil and slip the wire
into the feeder and torch sheath. Remove the gas nozzle
and unscrew the contact tip (located on the end of the
torch). Turn on the machine. Press the torch trigger
until the wire protrudes or use switch (13) . Tighten the
contact tip and replace the gas nozzle.
3.4 GAS CONNECTION
- Secure the welding grade shielding gas cylinder
in an upright position by chaining it to a suitable
stationary support to prevent falling or tipping.
- Connect the regulator inlet connection to cylinder
or pipeline and tighten it firmly but not excessively,
with a suitable spanner.
- Connect and tighten the outlet hose firmly.
- Open the reducer of the cylinder and adjust the gas
flow to 8 – 10 l/min.
CAUTION: Make sure the gas used is compatible with
the material to be welded.
