3.4 Gas Detection
Check whether there is gas or not, and gas flow rate.
1. Touch “Gas Detection” button, LED light will be on.
Gas starts to flow. Then gas flow ratecan be checked. Gas detection function will be shut downautomatically
30 second later.
2. Press thebutton again,light LED will be off and gas detection stopped.
3.5 Synergic/Separate
Under the synergic mode
，
the LED light will lasts on.
Short-Pressingthisbutton, theright nixie tubewill show switch between synergic correction value and
synergic voltage
Synergic：Welding voltage varies along with the changes of current. Standard synergic voltage modified
value is 0. Voltage modification range is ±30.
The rated voltage relationship as below:
The rated welding voltage=the synergic voltage＋the voltage modification range %)×(thesynergic voltage)
Separation：Current& voltage is adjusted separately.
1. Long-pressing "Function" key more than 3seconds, then enter into internal menu.
2. Turn the left knob and regulate to FC3. (Synergic/Separation Switch）
3. Turn the right knob toswitch Synergic or Separation mode. The default value is OFF. （Synergic）
Attentions
Under the Synergic function, the voltage normal point should be set to zero. Current and voltage matching relationship
specified by the manufacturer is realized under normal point.
3.6 Arc Dynamics
Arc dynamicsis to adjust hardness of arc.
Harden the arc by adjusting in positive direction and soften arc by negative direction
Arc dynamics are described as shown in Table 3-1 andFig.3-3.
Table3- 1Arc Dynamics Description
0 (Default value) Universal use, Default value
0~9 (hard arc)
Deep and easy penetrated. Suitable for full position welding and high speed welding. The arc
stability also could be ensured under extended cable
Shallow and not easy to be fully penetrated. The values are suitable for welding of thin plate.
Positive direction Negative direction
0
