OPERATION
FLEXCUT™ 80
MECHANIZED CUTTING
Mechanized Torch Installation
It is recommended that the FLEXCUT™ 80 mechanized torch be
installed on a positioner with an arc voltage control capable of
maintaining the cutting arc voltage within 1 volt. The positioner must
be rigid to ensure cut quality and a torch collision sensor is highly
recommended.
Installing the Mechanized Torch Consumables
To install the torch parts, perform the following
steps:
Note: Do not over tighten the consumables! Only tighten until the
parts are seated properly.
1. Inspect the threads on the torch body and retaining cap and
clean as necessary.
2. Install the electrode (1) into the torch body using a standard 3/8"
socket. Do not over tighten! 11-13 in-lbs is recommended.
Torque must never exceed 15 in-lbs.
3. Thread the shield cap (5) onto the retaining cap assembly. (4)
4. Insert the swirl ring (2) into the nozzle. (3)
5. Place the swirl ring / nozzle assembly into the retaining cap.
6. Thread and tighten the retaining cap assembly onto the torch
body. (6)
Removing the Torch Consumables
To remove the torch consumables, perform the
following steps:
1. Remove the retaining cap from the torch.
2. Remove the swirl ring and nozzle from the retaining cap.
3. Separate the shield cap from retaining cap.
4. Remove the electrode from the torch body using the 3/8" socket.
5. Remove the swirl ring from the nozzle.
Contaminants such as dirt, metallic dust, oil and moisture present on
the surface of the electrode and/or torch body can cause electrical
arcing between these components and ultimately result in failure of
the torch and consumables. In order to avoid damaging the torch
and/or consumables, adhere to the following guidelines:
1. Ensure that the air supplied to the torch does not contain conta-
minants such as debris, moisture and oil.
2. Ensure that the torch cathode body and electrode body are clean
prior to assembling the consumables into the torch. Wipe away any
contaminants with a dry, lint free cloth.
3. Be sure that the consumables are properly tightened when
installing them into the torch to ensure that there is no gap
between the electrode body and cathode body. Check the
installation of the consumables before the start of each work shift
and frequently during each work shift to ensure that the parts have
not become loose as a result of normal operation.
4. Inspect the surfaces of the cathode body and electrode body to
ensure no contaminants have collected during operation.
