Bead is 
intermittently too 
thin or too thick

1.  Inconsistent travel speed
2.  Output amp setting incorrect

1.  Carefully watch and control the width of the molten weld bead
2.  Adjust output amp setting or change to smaller diameter electrode

Ragged 
depressions at 
edge of weld

1.  Travel speed too fast
2.  Arc length too short
3.  Output amp setting too high

1.  Watch orange molten weld puddle and control bead width
2.  Practice running electrode across workpiece with welder OFF
3.  Reduce output amp setting

Weld bead does 
not penetrate 
base metal

1.  Inconsistent travel speed
2.  Output amp setting too low
3.  Electrode diameter too large

1.  Decrease and maintain constant travel speed
2.  Increase output amp setting
3.  Change to smaller diameter electrode

Electrode sticks to 
workpiece

1.  Arc length short
2.  Amp setting low
3.  Incorrect electrode

1.  Lift electrode to correct arc length as soon as arc is struck
2.  Increase amp setting or change to smaller diameter electrode
3.  Verify electrode is suitable for 62.5 V open circuit voltage

Electrodes sputter 
and stick

Damp electrodes

Use dry electrodes and store in dry location
