Poor welding properties
Cause:
Turbulence caused by too high a rate of shielding gas flow
Remedy:
Reduce amount of shielding gas,
recommended shielding gas quantity (l/min) = wire diameter (mm) x 10
(e.g. 16 l/min for 1.6 mm filler wire)
Cause:
Too large a distance between the welding torch and the workpiece.
Remedy:
Reduce the distance between the welding torch and the workpiece (recommended: 10-15 mm)
Cause:
Tilt angle of the welding torch is too great
Remedy:
Reduce the tilt angle of the welding torch
Cause:
Wirefeed components have incorrect diameter
Remedy:
Use wirefeed components with correct diameter
Poor wirefeed
Cause:
The braking force has been set too high
Remedy:
Reduce the braking force
Cause:
Hole in the contact tube is displaced
Remedy:
Change the contact tube
Cause:
Faulty wire feed liner in torch
Remedy:
Check the wire feed liner for kinks, dirt, etc.
Cause:
The wirefeed rollers are not suitable for the filler wire being used
Remedy:
Use suitable wirefeed rollers
Cause:
Feed rollers have the wrong contact pressure
Remedy:
Adjust the contact pressure
Cause:
The wirefeed rollers are soiled or damaged
Remedy:
Clean the wirefeed rollers or exchange them for new ones
Cause:
Inner liner wrongly laid or kinked
Remedy:
Replace inner liner
Cause:
Inner liner or wire inlet nozzle wrongly dimensioned
Remedy:
Ensure inner liner or wire inlet nozzle are correctly dimensioned
Cause:
Inner liner was kinked while being inserted
Remedy:
When inserting the inner liner, only handle it around the infeed tube
Cause:
AlSi filler wire: Filler wire damaged by the bronze insert
Remedy:
Teflon liner must reach the contact tube
Cause:
The inner liner has been cut too short
Remedy:
Replace the inner liner and cut it to the correct length
Cause:
Welding wire worn due to overly heavy contact pressure at the feed rollers
Remedy:
Reduce contact pressure at the feed rollers
Cause:
Filler wire contains impurities / corroded
Remedy:
Use high-quality filler wire with no impurities
