Droplets are splashing
* The voltage is too high.
* The gas nozzle is not cleaned
properly.
* Wire speed is set incorrectly.
Insufficient welding filling
* Welding speed is higher than it
should be.
* Wire feed speed is lower than
welding speed.
* Wire diameter is not suitable for
the job.
WELDING PROBLEMS
POSSIBLE CAUSES
Porous welding
*
The gas level is too low or too
high
.
* Splashed droplets accumulate in
the gas nozzle and cause insufficient
gas flow
.
* The air flow in the welding area
neutralizes the shielding gas
.
*
The distance between the tip of
the torch and the material being
welded is too large or the torch is
being used incorrectly.
*
The material to be welded may be
moist, oily, rusty
.
* Wrong shielding gas used.
Bad welding filling
*
Irregular use or incorrect contact
part is used.
* Low welding voltage selected.
* Irregular welding speed used
.
Uneven welding
*
Wire speed is very high compared
to the voltage value.
* Welding speed is very low
.
Penetration is insufficient
*
Wire feed speed is very low
compared to voltage
.
