5 INSTALLATION AND START-UP FOR MIG WELDING
WITH GAS
The welding machine must be installed by skilled
personnel.
Do not place the welding machine on floor with inclina-
tion greater than 10°.
Make sure that the supply voltage is 230V 50/60Hz and
a minimum of 30 amp service. If connected to a circuit
protected by fuses, use time dely fuse marked "D".Use a
plug Nema type 6-30P for 230 V and make sure that the
"green conductor" of the power supply cable is con-
nected to the ground or "earth" terminal.

• Position the cylinder on the support and fix it with the 2
straps; ensure that the straps are secured tightly to the
cylinder to prevent dangerous tilting.
• Connect the gas hose to the outlet of the pressure regulator.
• Open the side door.
Make sure the earth lead D, inside the reel compartment,
is connected to the negative pole see the instruction
plate placed alongside the + and - terminals).
• Connect the earth lead clamp D to the piece to be welded.
• Fit the wire coil on the support inside the compartment.
The coil must be fitted so that the wire unwinds in an
anticlockwise direction.
• Make sure the drive roller is correctly positioned according
to the diameter and type of wire used.
• Cut the welding wire with a well-sharpened tool, keeping
it between your fingers so that it cannot unwind, insert it
inside the pipe exiting from the gear motor and, with the aid
of a finger, insert it inside the steel tube until it comes out of
the adapter.
• Fit the welding torch.
After fitting the reel and torch, switch on the machine, select
the suitable synergic curve, following the instructions given
in the service functions (PROCESS PARAMS) paragraph.
Remove the gas nozzle and unscrew the current nozzle
of the torch. Press the torch button until the wire comes
out. BE CAREFUL to keep your face away from the end
lance while the wire is coming out, screw up the current
nozzle and fit the gas nozzle.
Open the canister adapter and adjust the gas flow to 8 –
10 l/min.
During welding, the display screen A displays the actual
work current and voltage. The displayed values may
be slightly different to those set. This can depend on
numerous different factors - type of torch, thickness
different to nominal thickness, distance between current
nozzle and the material being welded, and the welding
speed.
After welding, the current and voltage values remain
stored on the display A, where letter H (HOLD) is
