OPERATION
(18) With a small movement rotate the Gas (19) Now rotate the Gas Cup in the reverse
Cup forward so that the Tungsten Electrode direction to lift the Tungsten electrode from
touches the work piece. the work piece to create the arc.
(20) Release the trigger to stop the welding.
IMPORTANT! - We strongly recommend that you check for gas leaks prior to operation of
your machine. We recommend that you close the cylinder valve when the machine is not in
use.
§4.2.2 DC TIG Welding
The DC power source uses what is known as DC (direct current)
in which the main electrical component known as electrons flowin
only one direction from the negative pole (terminal) to the positive
pole (terminal). In the DC electrical circuit there is an electrical
principle at work which should always be taken into account when
using any DC circuit. With a DC circuit 70% of the energy (heat) is
always on the positive side. This needs to be understood because
it determines what terminal the TIG torch will be connected to (this rule applies to all the
other forms of DC welding as well ).
