MAINTENANCE
NOTE!
Regular maintenance is important for safe, reliable operation.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer
attempts any work to rectify any faults in the product during the warranty period.
6.1
Daily or as necessary
A regular programme of care and maintenance reduces unnecessary and expensive
downtime.
•
Each time a wire bobbin is changed, the welding hose should be removed from the
supply unit and cleaned with compressed air.
•
The wire end must not have sharp edges when inserted into the wire liner. This is
especially important when using PTFE wire liners.
Tips and nozzles
•
Remove the gas nozzle, spatter protector, tip adapter and contact tip.
•
Clean any spatter from the gas nozzle, tip adaptor and contact tip so that the shielding
gas can flow freely, thus eliminating the risk of a short circuit.
•
Check that the gas nozzle is free from defects. Damaged or worn tips/nozzles should be
replaced with a new one.
•
The spatter protector in the gas nozzle must be replaced once its front end wears thin.
•
Select contact tip to suit wire dimension.
•
Mount the fittings.
•
Welding spray in the gas nozzle diminishes gas protection and increases the danger of
spark-over. Clean the equipment on a regular basis and use sparing amounts of welding
paste or welding spray.
•
The gas nozzle and the front parts of the welding torch must be kept free of weld spatter.
Spray anti-spatter agent at an angle into the gas nozzle from two directions. Use ESAB
anti-spatter agent to prevent spatter sticking.
NOTE!
Never spray directly into the nozzle. Too much spray can attract dirt.
•
The contact tip should be replaced when the hole opening is worn to more than double
the wire diameter. Make sure that the new tip is screwed into the base.
