MIX TIG Control
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
MIX TIG Frequency (Hz):
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.
DC TIG-Pulse
High Speed DC TIG-Pulse Controls
• PPS Pulses per second (Hz):DC = 0.1 – 5,000 PPS
• % ON – % Peak Time:5 - 95% (Controls the amount of time during each pulse cycle at the PEAK amperage.)
• Background Amps:5 – 99% (Sets the low-pulse amperage value as a % of the Peak Amps.)CONVENTIONAL PULSED TIG
HIGH SPEED PULSED TIG
Typically from 1 to 10 PPS. Provides a heating and
cooling effecton the weld puddle and can reduce
distortion by lowering the average amperage. This
heating and cooling effect also produces adistinct
ripple pattern in the weld bead. The relationship
between pulse frequency and travel speed determines
the distance between the ripples. Slow pulsing can
also be coordinated with filler metal addition and
can increase overall control of the weld puddle.In excess of 40 PPS, Pulsed TIG becomes more
audible than visible—causing increased puddle
agitation for a better as-welded microstructure.Pulsing the weld current at high speeds — between
a high Peak and a low Background amperage —
can also constrict and focus the arc.This results in
maximum arc stability, increased penetration and
increased travel speeds(Common Range:100–500PPS).The Arc-Sharpening effects of high speed
pulsing are expanded to new dimensions. The ability
to pulse at 5,000 PPS further enhances arc stability
and concentration potential — which is are required./SPECIFICATIONS
