PSI PRO 315 A 400 V DC MIG/MAG TIG/MMA
If it is required to reduce heat input to the weld, as in welding thin parts, the welding voltage should be
decreased by performing the standard setting operations. In this case, voltage pulse parameters will be
adjusted automatically according to the set welding voltage, and the operator can control the reduction
of the heat input as compared with the preceding mode by simultaneously varying the voltage pulse
amplitude and duty cycle.
The aforementioned parameters should be set differently for different welding processes, depending on
the requirements of the operator. Operations required to set these parameters in the current welding
process are described in
Section 6.1.

6. SETTING THE WELDING UNIT
When no button on the front panel of the welding unit is pressed, the digital display of the unit shows
the value of the basic parameter of the current welding process:
1.
Welding current in the manual arc welding process
(MMA)
2.
Welding current in the argon shielded tungsten-arc welding process
(TIG)
3.
Welding voltage in the semiautomatic arc welding process
(MIG/MAG)
4.
Welding wire speed in the semiautomatic arc welding process
(MIG/MAG)
The buttons
(1)
on the front panel are responsible for changing the value of the selected function or
basic welding parameter.
The button
(3)
on the front panel of the source is responsible for the following:
1.
The choice of any function in the current welding method to unblock the devices should be
kept pressed button
(3)
for more than 5 seconds.
2.
Resetting all functions to the factory settings in the welding method being used should
be kept
pressed for more than 10 seconds;
(The device does not reset the settings in other methods).
The button
(4)
on the front panel of the multifunction machine is responsible for the following:
1.
The choice of welding method (quick press);
The button
(10)
on the front panel of the source is responsible for the following:
1.
The choice of any feeder function in the MIG/MAG welding method, in order to unblock the
feeder, keep the button
(10)
pressed for more than 5 seconds.
Buttons
(8)
on the front panel are designed for changing the value of the function or basic parameter of
wire feeder.
