MISADJUSTMENTS(S)
RECOMMENDED COURSE
OF ACTION
Stick electrode "Blasts Off"
when arc is struck.
1. Weld current may be set too high for
electrode size. Reduce current
control setting, or use a larger
diameter electrode.
2. Dirty
materials
3. Hydrogen in weld (present on
electrode coating).
Stick electrode "sticks" in
the weld puddle.
1. The weld current may be set too low.
Increase the current control setting or
use a smaller diameter electrode.
2. Arc too short.
Excessive spatter
1. Long arc
2. High current
Craters
1. Fast movement of the electrode
away from piece.
Inclusions
1. Poor cleanliness or distribution of
the Welding passes.
2. Improper movement of the electrode.
Insufficient penetration
1. High progression speed.
2. Welding current too low.
3. Narrow chamfering.
Porosity
1. Humidity in electrode.
2. Long arc.
If all recommended possible
areas of misadjustment
have been checked and the
problem persists, Contact
your local Authorized Field
Service Facility.
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely,
