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 :
NOVOMIG 110
X%-max 6% - 85A
12% 65A
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 POSSIBLE CAUSES REMEDIES
The welding wire speed is not
constant.
Debris is blocking up the opening. Clean out the contact tip or change it
and replace the anti-adherence product.
Ref.041806
The wire skids in the rollers Check the roller pressure or replace it.
- Wire diameter incompatible with roller
- Covering Wire guide in the torch incompatible
The wire-feeder motor doesn’t operate. Reel or roller brake too tight Adjust the brake and rollers.
Electrical supply problem. Check the power switch is in the "On" position.
Bad wire feeding. Covering wire guide dirty or damaged Clean or replace
Reel brake too tight Release the brake
No welding current Bad connection to the main supply Check the mains connection and ensure the
supply is 230V (1PH) power socket.
Bad earth connection. Check the earth cable (connection and clamp
condition).
The wire jams (after the rollers). Guide wire sheath crushed. Check the sheath and torch body.
Wire jammed in the torch Clean or replace.
No capillary tube. Check the presence of capillary tube.
Wire speed too fast Reduce the wire speed.
The welding bead is porous. Nozzle dirty Clean or replace nozzle.
Poor quality wire. Use suitable wire for no gas welding.
Work piece in bad condition. (rust, etc…) Clean the metal before welding.
The arc produces a lot of sparks Arc voltage too low or too high. See welding settings.
Bad earth connection. Adjust the earth cable for a better connection.
