16. 2#: “4T/2T” selection button:
Selecting “4T/2T” procedure functions, TIG welding divides into “2T” action
(non-self lock) and “4T” action (self lock), both AC(PULSE TIG/TIG) and
DC(PULSE TIG/TIG) can realize “4T/2T” selection. “2T” means to start welding
when press the torch switch and stop welding when the torch switch is released.
“4T” action style means output ARC striking current when press torch switch for
the first time, current up to standard welding current while releasing the torch
switch. Press the torch switch again after welding is finished, and then welding
current begin down to end-ARC current and retain it. The welding machine stops
outputting current after releasing torch switch for the second time.
17. 3#: “AC/DC” selection button:
selecting “AC/DC” functions, TIG welding divides into AC welding and DC
welding, the indicator on position stands for current status.
18. 4#:parameter adjustment(towards the left):
You can choose any procedure function among “GAS PRE-FLOW/GAS
POST-FLOW, STARTING AMP./FINAL AMP. ,CURRENT UP SLOPE/CURRENT
DOWN SLOPE,TIG, AC/PULSE FREQUENCY, BASE AMP./PEAK AMP.,CLEAN
WIDTH/CLEAN SCOPE /PULSE WIDTH” by press this button . The illumination
indicator stands for the current status you are choosing. The indicator will
illuminate from the right to left in order while you press. Also when it is MMA
welding, the button can adjust (just decrease) ARC force.
19. 5#:parameter adjustment(towards the right):
You can choose any procedure function among “GAS PRE-FLOW/GAS
POST-FLOW, STARTING AMP./FINAL AMP. ,CURRENT UP SLOPE/CURRENT
DOWN SLOPE,TIG, AC/PULSE FREQUENCY, BASE AMP./PEAK AMP.,CLEAN
WIDTH/CLEAN SCOPE /PULSE WIDTH” by press this button . The illumination
indicator stands for the current status you are choosing. The indicator will
illuminate from the left to right in order while you press. Also when it is MMA
welding, the button can adjust (just increase) ARC force.

20. 6#: “Decrease button”:
After choosing the procedure function, the current
status are set, then you can press this button adjust its parameter. For example:
GAS PRE-FLOW indicator on, adjust “ADJUSTMENT PAR.” 6# button to set
“GAS PRE-FLOW/ GAS POST-FLOW” time (3~0s/99.9-0s); When the
“STARTING AMP.” indicator on, adjust “ADJUSTMENT PAR 6#.” button to set
STARTING AMP. /FINAL AMP. current (315/270/250~/15A); and using the same
way to adjust beforehand for the followings: “CURRENT UP SLOPE/CUR-
RENT DOWN SLOPE” time (15~0S), “TIG” (315/270/250~15A), “BASE AMP./
PEAK AMP.” current (315/270/250~/15A) /“PULSE WIDTH ”(99%~1%), “AC”
(100~20HZ) /“PULSE FREQ.” (500~0.2HZ(DC), 20~0.2HZ(AC)); “CLEAN
WIDTH (+40~ -40%) ”/“CLEAN SCOPE (30~ -15%)”. Long time pressing this
button can realize speed adjustment. This button just can adjust these parameters
from high to low. Also when it is MMA welding, adjust this button can decrease
the welding current.
21. 7#”Increase button”:
The similar to 6# “decrease button, once the current status are set, then you can
press this button adjust its parameter from low to high (opposite adjustment
comparing with 6#). This welding machine can auto-save data when it is power off,
which could be used directly of next time. Also it can used for adjusting welding
current (from low to high) when the STICK is used.
OPERATION
Note:
Before beginning, please read and understand all the safety
precautions and especially the section “Specific Safety Rules”.
1. Open the door of water cooling system and Pour into some water .
2. Connect the TIG torch control, cable plug, water outlet and gas outlet hose as.
Twist to lock in place.
3. Plug the cable of the Grounding Clamp into the welder and secure the clamp to
a clean, exposed metal part of the workpiece.
