10 Same
electrode
cap types on the
same welding gun
have
different
service lives.
One electrode may be in
contact with the milling tool.
By changing the programming,
make sure that both electrodes
are in contact with the tool at
the same time.
Due to the welding task, the
electrodes are subjected to
different stresses. This can e.g.
caused by inadequate cooling
or positional error of the pliers.
Check welding process and
adjust if necessary. If this does
not help, align the cap
replacement with the shorter
life of the cap.
11 Electrode effective
area is too small
and / or not round.
Wrong milling insert
Check
part,
replace
if
necessary.
Swinging the milling cutter
through unstable assembly
and/or too long milling.
Ensure secured correctly to the
stand or swivel. Shorten the
milling time.
12 Mill tool forms
chatter marks on
the electrode.
Wrong milling tool
Check
part,
replace
if
necessary.
The welding gun does not close
over the center of the milling
tool.
Check
programming
and
correct if necessary.
Set angle of the electrode
when milling too flat.
Check
programming
and
correct if necessary.
Swinging of the milling tool by
unstable assembly
Ensure secured correctly to the
stand or swivel. Shorten the
milling time.
Electrodes are not aligned
correctly.
Readjust electrode holder.
