for vertical bore welder axis welding
4.4.3 Setting the wire speed
Follow the manufacturer’s instructions for the customer-supplied wire feeder to set
the wire speed.
NOTICE
With 0.035" (.889 mm) wire, a wire speed of 250"/min equals
approximately 125 amps. This setting is recommended as a
baseline when starting welding. At a travel speed of 22"/min, the
bead size is approximately 0.115" in depth.
4.4.4 Checking the step setting
Do the following to check the step setting:
1. Check that the bore welder is clear of rotational obstructions.
2. Disconnect the wire feed
control cable.
3. Rotate the bore welder
spindle by connecting the
AC mains cable (but not
the wire feeder cable) and
using the
WELD
switch to
turn the spindle. If the pen-
dant is in use, push
ROT
/
JOG
on the remote control
pendant.
CAUTION
Failure to disconnect
the control cable in
step 2 could result in
unwanted weld
activity.
