Troubleshooting
12.1 Electrode welding
Troubleshooting table of the models EASY-STICK 121, EASY-STICK 141 and EASY-STICK 161:
S/N
Fault
Possible cause
Solution
1
No arc
Incomplete welding circuit
Check earth lead is connected.
Check all cable connections.
No power supply
Check that the machine is switched
on and has a power supply
2
Porosity - small cavi-
ties or holes resulting
from gas pockets in
weld metal
Arc length too long
Shorten the arc length
Work piece dirty,
contaminated or
moisture
Remove moisture and materials like
paint, grease, oil, and dirt, including mill scale
from base metal
Damp electrodes
Use only dry electrodes
3
Excessive Spatter
Amperage too high
Decrease the amperage or choose a
larger electrode
Arc length too long
Shorten the arc length
4
Weld sits on top, lack of
fusion
Insufficient heat input
Increase the amperage or choose a larger
electrode
Work piece dirty,
contaminated or
moisture
Remove moisture and materials like paint,
grease, oil, and dirt, including mill scale from
base metal
Poor welding technique
Use the correct welding technique or seek assi-
stance for the correct technique
5
Lack of penetration
Insufficient heat input
Increase the amperage or choose a larger electrode
Poor welding technique
Use the correct welding technique or seek
assistance for the correct technique
Poor joint preparation
Check the joint design and fit up, make sure the ma-
terial is not too thick. Seek assistance for the correct
joint design and fit up
6
Excessive penetration-
burn through
Excessive heat input
Reduce the amperage or use a smaller electrode
Incorrect travel speed
Try increasing the weld travel speed
7
Uneven weld
appearance
Unsteady hand, wavering
hand
Use two hands where possible to steady up, practise
your technique
8
Distortion - movement
of base metal during
welding
Excessive heat input
Reduce the amperage or use a smaller electrode
Poor welding technique
Use the correct welding technique or seek assi-
stance for the correct technique
Poor joint preparation and
or joint design
Check the joint design and fit up, make sure the ma-
terial is not too thick. Seek assistance for the correct
joint design and fit up
9
Electrode welds with
different or unusual arc
characteristic
Incorrect polarity
Change the polarity, check the electrode manufactu-
rer for correct polarity
