3.2.1 POWER SOURCE PANEL FUNCTION DETAILS
Figure 3-4 Welding mode selection zone
Welding mode selection zone contains welding mode
indicators and selection key.
Welding modes include DC TIG, Pulse TIG, DIC MMA
(TIG400 has no pulse TIG function). Press the welding
mode selection key to choose the according welding
mode. The welding mode being selected is the
according mode with its indicator lighting up.
Remark: welding mode indicator will light up during
welding processing (when there is welding current).
Figure 3-6 MMA parameters selection zone
This zone contains parameters selection and VRD
switch-over
1.Press
to switch MMA parameters; it can be
circulated among HOT START、CURRENT、ARC
FORCE
2. Press VRD and indicator is on; MMA will enter VRD
mode and OCV is 19V.
Remark: not available for TIG and TIGP.

Figure 3-5 TIG selection zone
This zone include 3 parts: TIG operating mode
selection, water cooling switch key, arc ignition switch
key (HF& contact)
1. TIG welding modes: 2T、4T、REPEAT、SPOT,
Press
to select the according welding mode.
2.TIG water cooling witch key
(1)press the key and indictor is on to enter water
cooling mode. In full set welding system, water tank
will give water flow signal and check whether there is
a water-lack; there is E-5 warning and is with no
output in case of water lack; please check if
everything is back to normal and observe whether
there is E-5 when under TIG.
