The machine will calculate that while maintaining the set pulse difference, the
average welding current will be maintained at the main welding current of 18V (as set),
respectively the heat input to the weld will be the same as 18V, but the stability of the
welding process, the mixing of the weld pool and weld penetration will change. This is a
very important condition for the user to accurately estimate the amount of change in weld
pool's heat input.
If the task is to reduce the heat input to the weld using pulse mode, e.g. when welding
thin metals, then it is necessary to reduce, in a standard way, the main source voltage,
while the pulse amplitude and pauses set earlier will automatically adjust to this voltage.
Therefore the user will clearly understand how much the current heat input to the weld is
reduced compared to the previous mode, while changing in any combination the pulse
power and "duty ratio" to obtain the desired process. This task is not simple, because
several parameters are regulated at once.
These parameters are set differently in each situation, according to the welder's
requirements. To change the value of any function in the current welding mode, see section
6.1.
5.9 MOTOR SWITCH-OFF FUNCTION
This optional feature to turn off motor operation may not be present in the wire
feeder menu, because when there is communication between the control units, the
machine itself decides whether to turn the motor on and off in a particular welding mode.
This parameter must be in the "ON" position for proper operation of the semi-automatic
machine.
6. SELECTING AND CONFIGURING MACHINE FUNCTIONS
If you do not press any buttons on the front panel, the machine displays the value of
the main parameter of the current welding mode on the digital display on the left side:
1) In the MMA mode
–
welding current;
2) In the TIG mode
–
welding current;
3) In the MIG/MAG mode
–
welding voltage.
During MIG/MAG welding, the left indicator shows the actual current value resulting
from the following factors: the wire diameter used, the voltage set at the source, the wire
feed speed set on the wire feeder, the gas used, the material and thickness of the piece
being welded, etc. The value is displayed for 8 seconds after welding is finished, so that the
welder can double-check it without assistance. And the digital display on the right side in
the same MIG/MAG mode shows the wire feed speed in m/min.
Button
3
on the front panel of the machine is used to select the source function in the
current welding mode, and button
11
is used to select the function of the feeder in
MIG/MAG mode. This will be discussed in paragraph 6.1.
Button
4
on the front panel of the machine is used to select the welding mode. This will
be discussed in paragraph 6.2.
Buttons
1
on the front panel of the source are used to change the current value on the
digital display on the left side.
