14.Function Sequence

1.Gas pre-flow time(TIG)
   Absolute setting range 0.1s to 5.0s (0.1s increments).
2.Ignition current(TIG)
   Percentage of the main current.
   4T(HOLD)
   Setting range 1% to 100%(1% increments).
3.Up-slope time(TIG)
   Setting ranges:0.00s to 20.0s(0.1s increments).
   The up-slope time can be set separately
   for non-latched and latched.
4.Main current(TIG)/pulse cuttent
  I min to max(1 A increments)
  Main cuttent(MMA)
  I min to I max(1 A increments)
5.Pulse time
   Pulse time setting range:0.01s to 9.99s(0.01s increments)
   TIG pulses
   The pulse time applies to
   the main cuttent phase(AMP) for pulses.
   TIG AC Special
   The pulse time applies to the AC phase for AC special.

6.Pulse break time
   Pulse break setting range:0.01s to 9.99s
   (0.01s increments).
   TIG pulses
   The pulse break time applies to the secondary
   current phase(AMP%).
   TIG AC Special
   The pulse time applies to the AC phase for AC special.
7.Secondary current(TIG)/pulse pulse pause current
   Setting range 1% to 100% (1% increments).
   Percentage of the main current.
8.Down-slope time(TIG)
  0.00s to 20.0s (0.1s increments).
  The down-slope time can be set separately
   for non-latched and latched.
9.End-crater current(TIG)
   Setting range 1% to 100%(1% increments).
   Percentage of the main current.
10.Gas post-flow time(TIG)
   Setting ranges:0.1s to 20.0s(0.1s increments).

Features of MIX TIG:

The AC current can get a very good clearance, and
DC current can get a deeper penetration. Use the
MIX TIG we can get an excellent Arc Concentration,
can be carried out the excellent welding performance
from thin to thick plate.
1) Nice weld appearance, deep penetration.
2) Excellet Arc Concentration..
3) Substantially reduce the electrode consumption.

MIX TIG Frequency (Hz):

the cycle time of MIX
TIG in 1 second. Adjustable range: 0.1-10Hz.

MIX TIG Balance (DC) %:

DC Balance (%) = (tad/Tmix) x 100

AC Frequency control Controls the
width of theControls the width of the
arc cone.Increasing the AC Frequency
provides a more focused arc with
increased directional control.

Note: Decreasing the AC Frequency
softens the arc and broadens the
weld puddle for a wider weld bead.

AC Balance Control
Controls arc cleaning action.
Adjusting the % EN of the AC wave
controls the width of the etching
zone surrounding the weld.

Note: Set the AC Balance control
for adequate arc cleaning action
at the sides and in front of the weld
puddle. AC Balance should be fine
tuned according to how heavy or
thick th eoxides are.

Independent AC Amperage Control
Allows the EN and EP amperage
values to beset independently.
Adjusts the ratio of EN to EP
amperage to precisely control heat
EN amperage controls the level of
penetration, while EP amperage
dramatically effects the arc cleaning
action along with the AC Balance
control.
