Liner replacement.
Liners will give a good service life if maintained at regular intervals. This is done by clearing debris and dust from the Liner with a
clean and dry air supply inserted into the Liner. Wet air will corrode the internal surface of the liner.
It is best to blow the liner from the wire entry point of the liner because during operation, debris and dust is generally carried forward
towards the neck end of the Liner. Blowing from the opposite direction will push the debris into the Liner.
When a liner is due for replacement there are a number of points to note.
Steel Liner replacement
• Lay the torch out straight, ensuring it is not twisted.
• Unscrew the Liner nut.
• Remove the old Liner.
• Uncoil the new liner and feed it into the torch until resistance is felt from the front-end liner nipple. You can also check the
Liner has reached the end of its travel by viewing the liner end through the viewing holes in the liner nipple.
• Measure the excess liner sticking out from the rear-end.
• Remove the Liner
• Cut the excess liner material but leave an extra 5mm of liner. This added 5mm to the Liner length will ensure the liner is
always under slight compression within the torch.
• Grind the cut end to an inclusive angle of 40 degrees; the liner cut end must be ground to an inclusive angle of 40 degrees
to ensure the liner beds into the front-end fittings.
• Gently feed the Liner into the torch taking care not to bend or “kink” the liner.
• Tighten the Liner nut.
Teflon or PA Liner replacement
•
Lay the torch out straight, ensuring it is not twisted.
•
Unscrew the Liner retaining nut
•
Remove the old Liner.
•
Uncoil the new liner , and cut the end to a 40-degree
inclusive angle. This is to ensure the minimum clearance
between the liner and the liner nipple
• Gently feed the Liner into the torch taking care not to
bend or “kink” the liner until resistance is felt from
the front-end liner nipple. You can also check
the Liner has reached the end of its travel by viewing
the liner end through the viewing holes in the liner nipple.
• Slide the clamping collet , O-ring , and Liner retaining nut over the new Teflon liner ,
assemble the liner retaining nut and tighten.
• Measure the excess liner sticking out from the rear-end to the machine drive rolls and cut the liner directly in front of the wire
feeder drive rolls . Cut this end to a 40-degree inclusive angle to give the closet clearance to the drive rolls.
