BASIC WELDING GUIDE 4-8 Manual 0-5420
FAULT CAUSE REMEDY
6 Weld cracking A Weld high carbon steel without
pre/post heat treatment
A Have sufficient pre/post heat treatment before
welding high carbon steel.
B Incompatible filler metal used
to the base metal
B Use correct filler metal.
C Weld beads too small C Decrease travel speed.
D Weld penetration narrow and
deep
D Reduce current and voltage and increase MIG
Gun travel speed or select a lower penetration
shielding gas.
E Excessive weld stresses E Increase weld metal strength or revise design
F Excessive voltage F Decrease voltage.
G Cooling rate too fast G Slow the cooling rate by preheating part to be
welded or cool slowly.
7 Cold weld puddle A Welding voltage too high A Decrease voltage or increase the wirespeed
control.
B Loose welding cable
connection
B Check all welding cable connections.
C Low primary voltage C Contact supply authority.
D Fault in power source D Have an Accredited ESAB Service Provider to
test then replace the faulty component.
8 Arc does not have a
crisp sound that short
arc exhibits when the
wirefeed speed and
voltage are adjusted
correctly.
The MIG Gun has been
connected to the wrong voltage
polarity on the front panel
Connect the MIG Gun to the positive (+)
welding terminal for solid wires and gas
shielded flux cored wires. Refer to the
electrode wire manufacturer for the correct
polarity.
9 Poor weld result from
setup chart parameters
A Incorrect welder setup, polarity,
shielding gas, wire type and
size
A Check to make sure that the welder is set up
correctly; also check polarity, shielding gas,
wire type and size.
B Contact tip has arc marks in the
bore causing excessive drag on
the wire
B Replace the contact tip with only a Genuine
Velocity contact tip.
