®
Maintenance
The HELIX M627 weld head is designed for trouble-
free operation and normally requires minimal
preventive care and cleaning. This section provides
instructions for maintaining user-serviceable items.
The suggested repair procedure for all such items is to
remove and replace defective assemblies or parts.
When users and/or service personnel are not familiar
with electrical and electronic equipment, the product
should be returned to the factory or serviced by factory
authorized representatives.
Maintenance Schedule
The maintenance schedule is suggested as a guideline
for proper system maintenance. More stringent main-
tenance requirements may be required depending on
the work being performed and the requirements of the
customer for whom the work is performed. All mainte-
nance schedules are based on a 40-hour work week.
Any excess play in parts or equipment should be noted
and reported to an authorized repair facility. Any
abnormal activity, such as motor hesitation, clicking or
other noises, or anything out of the ordinary should be
noted and reported to an authorized repair facility.
Every Shift
• Check lines, cables, and belt for loose con-
nections and worn areas.
• Change out expendables as needed (wire guide
tip, collet, etc).
• Check torch height motion and travel for slop or
wearing parts.
Monthly
• Release the clutch latch and verify that the torch
motion assembly moves smoothly around the
workpiece.
• Examine all cable connections to verify that there are
no gas leaks, and that all cables are seated correctly
and that there is no visible wear and tear to any con-
nector or associated cables.
•
Check over all weld head components for any
signs of damage or wearing.
Ensure weld head gears are clean and clear of
•
debris.
• Check for wear of drive rolls on wire feeder.
Semi Annually
• Based on a 40-hour work week it is recommended
that the belt be replaced every six months.
• Verify that all motors are working correctly without
strain. Listen to the motors to confirm that there is no
excess noise or grinding.
