TIG LIFT
The DC TIG welding requires a protective gas (argon).
Follow the steps as below :
1.
Connect the earth clamp on the positive pole (+).
2.
Connect a torch "valve" negative polarity (-).
3.
Connect the pipe gas torch on the gas cylinder
4.
Select TIG mode
using the selector button
.
5.
Adjust the wished current (display
) using the keys
.
Advice : Take 30A/mm as a default setting and adjust according to the part to weld.
6.
Set the gas flow on flewmeter of the gas cylinder, and then open the valve of the torch
7.
To boot :
a-
Touch the electrode on
the welding part
b-
Raise the electrode 2 to 5
mm of the part to be welded
8. At end of welding :
Up 2 times the arc (up-down-up-down) to trigger the automatic fade (see paragraph below). This
movement must be performed in less than 4 sec, at a height of 5 to 10 mm. Then close the valve to
stop the torch gas after cooling of the electrode.
Automatic Arc slope with time adjustable
Function activation :
This corresponds to the end of welding time required for the gradual decline in the welding current until the
stop of the arc. This function helps to avoid cracks and craters at end of welding.
1-
Press 3 seconds on the selector button
2.
Set the automatic arc slope you wish from 1 to 10 sec (display
) using key
.
3.
Validate the required figue by pressing the selector button
.
