DUTY CYCLE & WELDING ENVIRONMENT IN USE
• The machine has a "constant output" (constant voltage) in MIG/MAG mode; and a "dropping output" (constant current) in MMA
mode. The duty cycles following the standard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below:
X @ 40°C
(T cycle = 10 min)
GOLDMULTI 140 - MIG/MAG
GOLDMULTI 140 - MMA
Note : The machine's duty cycle has been tested at room temperature (40°C) and has been determined by simulation.
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!
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.

REMEDIES
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-com-
patible.
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
condition).
Check the torch trigger / replace torch
Check the sheath and torch body.
Clean or replace.
Check the presence of capillary tube.
Reduce the wire speed
