TIG WELDING
TIG welding works on same principle of arc welding. In a TIG
welding process, a high intense arc is produced between tungsten
electrode and work piece. A shielding gas (Argon) is also used which
protect the weld surface from oxidization.
▪ Open the shielding cylinder and set the required gas flow using
the pressure (flow) adjustment knob on the regulator.
(Check out the table on pg.no.11 for gas adjustments)
▪ Press the switch of TIG torch, electromagnetic valve is started.
Sound of HF arc striking can be heard, at the same time argon is
flowing from torch burner.
Before welding user must press switch of torch several seconds
NOTE:
until all of air is be drained out.
▪ When welding is over, argon will still flow out in several seconds to
protect welding spot before cooed down. So, the torch must be kept
on welding place some time, before arc has been extinguished.
▪ Set suitable welding current and make sure welding current is
adequate to thickness of work piece and process demand.
▪ Maintain 2-4mm from tungsten electrode to work piece, press
switch of torch, burn and strike arc, sound of HF arc-striking will
be diminished. The welding machine can be operated now and the
operation can be conducted with the help of a filler rod.
