WELDER INFORMATION (cont.)
The machine allows you to set parameters: Ramp-Up, Burn-Back, Pulse and Frequency.
Ramp-Up: allows you to set how many seconds you want to
reach the set speed of the wire. During this time, there will be a
gradual increase of the wire speed. To set this parameter, press
the knob “ENC-2” until ‘r’ appear on display “DISP-2”, to change
the value turn “ENC-2”.
Burn-back: adjusts the remaining length of the wire from the
end of the welding torch. To set this parameter, press the knob
“ENC-2” until ‘b’ appears on display “DISP-2”. Changing the
length increases or descreases the time by turning “ENC-2”.
Pre-gas: adjusts the opening time of the gas (in seconds)
before the arc is striking. To set this parameter, press the knob
“ENC-2” until ‘g’ appears on display “DISP-2”, to change the value
of the opening time of the gas turn “ENC-2”.
Frequency: is used to set the frequency at which the pulses are
repeated over time. To set this parameter, press “ENC-2” until
you see ‘f’ on “DISP-2”. You must choose the “PULSE” for this
parameter to be displayed. During set up, if you do not make
any changes within 3 seconds, the display “DISP-2” will show
the value of the power set “PXX”
Pulse:
allows to carry out the welding with lower power in order to avoid the
heating of the workpiece, allows a speed of execution of the welding considerably
higher than in non-pulsed MIG. Furthermore, these is a drastic reduction of
sparks and fumes in welding with a considerable reduction in the time of rework
of welded pieces that have, in fact less deformation and an excellent degree of
finish. The pulse parameter is adjusted by the knob “ENC-2” (press the knob until
you see ‘o’ on “DISP-2”). The rotation of “ENC-2” allows you to choose between the
following values:
0 = no pulse, 5 = 50% power pulse and 10 = 100% power pulse
