- TWIN MIG Function
in double synergic mig for MULTI PLUS CONCEPT series machines.
For all mig synergic programs in addition at the mig pulse mode (PULSE) is aviable
the double pulse mig mode (TWIN)
This mode requires a variation of the arc in a continuous manner between two differ-
ent values at a frequency set by the operator. All parameters (current, speed of wire,
voltage, inductance, etc.). moving in synergy mode between the two different values .
The set of current that is set on the panel corresponds to the average value of the cur-
rent between the two different values .
In machine session select TWIN mode by press the SELECT (SW4) button untill fre-
quency LED ashes and display show “OFF”, appears to indicate that the frequency
mode is not active.By knob (ENC1) you can set the frequency of double pulse from
minimun of 0,5 Hz to a maximun of 4,0 Hz.
When the double pulse mode is active the frequency led ashes.
It si possible to select the two following functions : SPC and UP
“TWIN SPECIAL MODE ” FUNCTION : SPC
To select TWIN SPECAL MODE, in the following procedure.
By SELECT switch select the mode of frequency variation of the double pulse mode.
By knob (ENC1) increase the parameter untill display show “SPC” .
Now it is possible modify frequency, balance and level, for modify this parameter enter
in the thecnical parameter mode.
To enter in the thecnical parameter mode by press 3 seconds the SELECT (SW4)
button.
The double pulse frequency can be set from 0,5Hz to 4,0Hz
The Balance can be set from 5 to 90.
This parameter is the the percentage of pulse to the level of low current.
Th level is adjustable from 20 to 90 and represents the percentage of the current
value lower than the current value high.
“TWIN UP” FUNCTION : UP
This function is only present in some pulse programs.
This double pulsed function is useful to carry out any ascending welding vertical up.
To select TWIN SPECAL MODE, in the following procedure.
By SELECT switch select the mode of frequency variation of the double pulse mode.
By knob (ENC1) increase the parameter untill display show “SPC” and “UP” (remem-
ber, this function is enabled not in pulsed all programs)
“Twin -up” program works in double pulsed with the parameters of the synergic pro-

gram.
When TWIN UP program is active the “mode pulse “ led ashes.
if is working in the machine session it is possible change the welding mode, for to
return at the standard pulsed program must remove double pulse by setting to “0”
double pulse mode.
If is working with digital torch in the machine section, it is possible to save a program
with function pulse-up activated, and another program with “pulse-up disactived.
You can then enable or disable the function, by selecting diferents job.
Programs with function PULSE -UP:
