1.1 CLEAN BEFORE WELDING
Tungsten argon welding is very sensitive to surface contamination. Therefore ensure material is
clean and free from all contaminants including grease, paint, lubricants and rust. Use an appropriate
pre-cleaner if necessary.
1.2 DC ARGON ARC WELDING
①
Put Switch "19" (AC/DC) onto the position "DC", connecting the gas inlet pipe to inlet "21" of the
welding. Put switch "12" (MMA/TIG/CUT switch) onto the position "TIG".
②
Connect gas inlet pipe of the welder torch to argon output of welder "17".
③
Put the control plug of the welding torch in the argon arc control socket "18".
④
Testing gas: Switch on the power "2", open the argon bottle valve, press the torch switch, select suitable
argon flow.
⑤
Regulating the base current knob "4" (pulse current regulating to minimum, turning it anti clockwise to
the end).
Select welding current according to the
thickness of the material to be welded. Select
current down slope time and after flow time according to the current.
Notice 1:
The current indicating meter on the front panel is used to display the preset output
current level before welding and actual output level while welding: A lit display indicates that the
input power is turned on.
Notice 2:
When using the '
Adjustable foot control'
regulator, current will increase gradually when you
step on the '
Adjustable foot control
'
⑥Ensure
Tungsten electrode end is 2-3mm away from the welding material. Press the torch
switch,to strike an arc.
Notice 3:
During welding, with the "12. 2T/4T" mode on "2T" mode, the torch trigger should be held at
all times and must not be released. Otherwise the arc will extinguish.
⑧
.When the welding operation is finished, close the valve and turn off the power.
1.3 PULSE ARGON ARC WELDING
①
Select peak current and base current:
①
Current regulation: To carry out the pulse argon arc welding, the base current "4" should be lower than
pulse current "3" (current regulation). Rotate knob clockwise, to increase current.
②
Pulse frequency regulating: when the knob "6" is regulated clockwise, the frequency is high and pulse
speed is high; conversely the speed is low. The frequency changes between 0.5-25Hz.
③
Regulation of pulse width ratio: when the knob "5" is regulated clockwise, the width ratio increases,
conversely, it decreases. It can be selected between 0.1-0.9.
④
Regulation of up-slope time: when the knob "9" is regulated clockwise, the time increases. Conversely,
it decreases. It can be selected between 0-10S.
⑤
Regulation of down-slope time: when the knob "10" is regulated clockwise, the time increases,
conversely, it decreases. It can be selected between 0-10S.
⑥
Gas connection, testing, generating and post flow time use the same procedures as DC arc welding.
