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.
