7. Device commissioning
7.1 Power connections
The device is powered from a three-phase 400V/50Hz. The required protection is a slow-blow
fuse 16 A (FANMIG 280-4N) or 25 A (FANMIG 320-4N) with grounding. Plug type CEE FANMIG
280-4N 16 A 5-pin, FANMIG 320-4N 32 A 5-pin.
7.2 Welding torch connection
The welding torch should be connected with euro socket and screwed with a nut. The torch
insert and contact tip must refer to welded wire diameter – see torch catalogue.
7.3 Feed rolls in wire feeder (see table 4).
Each roll includes two notches - marking is stamped on roll side.
The notch must reflect the wire type and diameter. When changing the wire, make sure that the
correct roll is applied.
7.4 Mounting the spool on a feeder and wire feeding in the welding torch - button 1 as on
Fig.2.
The wire spool should be installed on the feeder so the wire unwinds from the bottom of the
spool and goes straight to feed rolls. If the spool is based on a metal basket, use a basket spo-
ol adapter. It is necessary to secure the spool so the basket does not touch the device metal
casing
Th spool’s braking force is controlled by a bolt inside the spool’s sleeve.
Unroll a short wire section from spool. Align the wire ending (cutting it off with off-cuts) and
guide it onto feeding roll with upper press mechanism is lifted! Than guide the wire through eu-
ro-socket and welding torch Press the pressure arm after inserting the initial 20 cm wire section
into the welding torch and continue feeding wire automatically by pressing torch button. It is
recommended to demount the gas nozzle and the tip contact when inserting the wire into the
torch. It is not allowed to use excessive pressure on the rolls, as it may lead to wire deformation
and feeding issues.
7.5 Gas hose and shielding gas flow.
Shielding gas hose connects the device to gas bottle. Gas reducer located on the cylinder
used for gas mixtures and argon. Cylinder should be located on the rear shelf of the device and
secured with a chain to prevent tipping over. Having the cylinder placed
and gas hose connected to the back of welding device, unscrew the cylinder valve and set
pressure level with the reducer. Gas flows out after pressing the button 2. Recommended gas
flow rate is 10 x the wire diameter and equals the gas flow in litres per minute
7.6 Aluminium welding
For aluminium welding use rolls with U-shaped notch (see table 4). Recommended wire type:
AlMg3 or AlMg5 and 1.0 mm diameter. Welding torch (suggested m length) should be accor -
dingly adjusted and have its insert replaced to a Teflon one and tip fitting the wire diameter.
Having the above operations completed and connection checked, the device is ready for ope-
ration.
