ROUTINE MAINTENANCE
Rou�ne maintenance consists of periodically blowing out the machine, using a low-pressure air stream,
to remove accumulated dust and dirt from the intake and outlet louvers, and the cooling channels in the
machine.
Check weld cables, control cables and gas hoses for cuts.
Clean and �ghten all weld terminals.
PERIODIC MAINTENANCE
Calibra�on of the PipeFab™ is cri�cal to its opera�on. Generally speaking the calibra�on will not need
adjustment. However, neglected or improperly calibrated machines may not yield sa�sfactory weld
performance. To ensure op�mal performance, the calibra�on of output Voltage and Current should be
checked yearly.
Clean the drive rolls and inner wire guide and replace if worn.
Blow out or vacuum the inside of the feeder.
Inspect the motor brushes every 6 months. Replace if shorter than 0.5" (12.7mm).
