PROBLEM
POSSIBLE CAUSE
SOLUTION
DEVICE FUNCTIONING PROBLEMS
The device is not connected to the
network supply, the device does not
receive input voltage, defective
switch
x
Check if the device is connected
is to the mains
x
Check the voltage at the socket at
assistance of a specialized meter
x
Check
the condition of the fuses
The machine
stopped welding,
the thermal
protector light turn
The safety system turn on to protect
the device
x
Check if there are Excessive
voltage.
x
Check if the machine is
overheated
if so - wait until the welding machine
cools down
PROBLEMS DURING WELDING PROCESS
(
MMA
)
Difficulties in
maintaining the arc,
breaking the arc
Wet electrode;
not suitable prepared welding
material
x
Check if the electrode was
prepared for welding and is stored
according to guidelines procedure.
x
Check if the material surface was
purified.
(
MMA
)
Excessive
Welding current too high; too
small electrode diameter;
incorrect connection of welding
poles; inadequately prepared
material for welding
x
Check if the welding current is within
the range specified by the electrode
manufacturer
x
Check that the electrode thickness is
selected according to the thickness of
the workpiece
x
Check welding polarity - is it
compatible with the electrode
manufacturer's recommendation
x
Check if the surface of the
(
TIG)
Excessive wear of
the fusible
electrode.
Insufficient shielding gas flow;
wrong electrode diameter up to
welding current; inverted
welding polarity, not suitable gas
shield.
x
Increase shielding gas flow
x
Replace
the non-fusible electrode
with an appropriate diameter
x
Check the welding polarity, the TIG
torch should be connected to the
negative pole, the ground clamp to the
positive pole
x
Check shielding gas - suitable
