1
Fuse F1
Fuse F1 protects the wirefeed motor
and motor drive board from over-
load. If Fuse F1 opens, the wirefeed
motor stops. Check for jammed wire,
binding drive gear, or misaligned
drive rolls. Correct problem and re-
place F1.
2
Fuse F2
Fuse F2 protects the VL-M4 internal
control circuits and the 115 vac sup-
plied to pin A of 17-pin receptacle
from overload. If F2 opens, all opera-
tion stops. Correct problem and re-
place F2.
3
Fuse F3
Fuse F3 protects the volt sense cir-
cuit from overload. If F3 opens, volt-
age feedback will be lost when using
a constant current power source with
the VL-M4 in the CC mode. Correct
problem and replace F3.
