GAS COUPLING
- Connect a pressure regulator to the gas bottle. Connect the welding machine (fig. F) using the pipes supplied, and place the two
clamps to avoid leakages.
- Set the gas flow by adjusting the dial located on the pressure regulator.
NB : to help facilitate the adjustment of the gas flow, operate the drive rollers by pressing the trigger of the torch (ensure that the
drive roller is completely loose so the wire is not fed through).
This procedure does not apply to «Gasless» welding mode.

RISK OF INJURY DUE TO MOVING PARTS
The wire feeders contain moving parts that may catch hand, hair, clothes or tools which can lead to injuries! Take extra
care.
• Do not lay a hand to swivel or moving components or parts to the drive!
• Ensure that the housing covers or protective covers remain closed during operation!
• Do not wear gloves when threading the filler wire and changing the filler wire spool.
ADVICE & THERMAL PROTECTION
This device is equipped with a ventilator regulated by the inside temperature. When the machine's thermal protection is activated, it
will not deliver any current. Orange light (Fig-V-2) will turn on until the temperature of the machine has returned to normal.
• Do not block/cover the ventillation holes, ensure free flow of air.
• Whilst in thermal protection mode leave the machine plugged into the mains after welding to allow it to cool.
General observations :
• Always respect the basic rules of welding.
• Always work in an adequately ventillated area.
• Do not work on a damp surface.

Clean out the contact batch or change it and replace
the anti-adherence product.
Ref.041806.
• Control the roller pressure or replace it.
• Wire diameter non-compatible with roller
• Covering wire guide in the torch non-compatible.
Release the brake and rollers.
Check that the power switch is in the "On" position.
Clean or replace
Tighten the drive roller knob
Release the brake
Check the mains connection and look if the plug is fed
by 230 V (1PH) power socket.
Check the earth cable (connection and clamp condi-
tion).
Check the torch trigger / replace torch
Check the sheath and torch body.
Clean or replace.
Check the presence of capillary tube.
