6.METHOD OF THE OPERATION
6.1.ARGON ARC WELDING(TIG)
6.1.1 CLEARING BEFORE WELDING
Tungsten argon arc welding is very sensitive to surface contamination of filled metal.
Therefore before welding is carried out,grease, paint and coating on the surface,lubricant for
machining and oxidized film should be removed.
1.2 DC ARGON ARC WELDING
①
.selector "10" onto the position " pulse off " ,Connecting the gas inlet pipe to inlet "21" of the
welding.
②
.Connecting gas inlet pipe of the welding torch to argon output of welder "17".
③
.Putting the aerial plug of the welding torch in the argon arc control socket "18".
④
.Testing gas: get the power of the welder ready and switch on the power "2", open the
argon
bottle switch and switch on the flow meter, press the torch switch, select suitable argon flow.
⑤
. .Regulating the base current knob "13". Selecting suitable welding current according to
thickness of the workpiece to be welded.. Selecting suitable 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 input
power is turned on.
Notice 2:
When using
'
Adjustable foot control
'
.regulating the current with sole. welding current
will increase gradually when you step at full tilt the '
Adjustable foot control
'
with sole.
⑥
. Tungsten electrode end is 2-3mm away from the welding workpiece. Press the torch
switch,arc striking will occur.
Notice:
During welding, when the" 12. 2steps/4steps switch"on "2 steps", switch of the torch
