DUTY CYCLE & WELDING ENVIRONMENT DURING USE
• The welding unit describes an output characteristic of "constant current" type. The duty cycles following the stan-
dard EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table below :
During intensive use (> duty cycle) the thermal protection can activate, if this event the arc switches off and the ther-
mal protection indicator switches on. The welding machine has a constant voltage output.
Note: The machines' 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!
TROUBLESHOOTING
SYMPTOMS
The welding wire speed is not
constant.
The wire-feeder motor doesn't operate.
Bad wire feeding.
No welding current
The wire jams (after the rollers).
The welding bead is porous.
The arc produces a lot of sparks

Clean out the contact tip or change it
and replace the anti-adherence product.
Ref.041806
Check the roller pressure or replace it.
- Wire diameter incompatible with roller
- Covering Wire guide in the torch incompatible
Adjust the brake and rollers.
Check the power switch is in the "On" position.
Clean or replace
Release the brake
Check the mains connection and ensure the
supply is 230V (1PH) power socket.
Check the earth cable (connection and clamp
condition).
Check the sheath and torch body.
Clean or replace.
Check the presence of capillary tube.
Reduce the wire speed.
Clean or replace nozzle.
Use suitable wire for no gas welding.
Clean the metal before welding.
See welding settings.
Adjust the earth cable for a better connection.
