Figure 6: Setup for TIG welding
1. TIG Startup
a. Prepare a tungsten electrode by grinding it to a point. There are many
instructions online for TIG electrode grinding.
b. Put a tungsten electrode in the TIG torch
c. Adjust the electrode so that it protrudes about 3/16" beyond the
ceramic tip.
d. Tighten the tail of the torch
e. Make sure the tungsten tip does not touch anything. It is easily broken
or contaminated.
f. Connect an argon supply to the gas inlet
g. Turn the machine OFF.
h. Make sure the MMA cable is not attached to the machine.
i. Attach the TIG cable to the machine. (Figure 6)
j. Put the TIG torch where its button will not be pushed accidentally.
k. Switch to TIG mode. (Figure 6)
l. Adjust current dial to 10 (welding thicker or larger pieces requires
more current)
m. Adjust post time to 4 (post time is the length of time the gas continues
to flow from the nozzle after the button or foot pedal is released.
Larger diameter tungsten electrodes require longer post times, to
protect the electrode while it cools. If you leave the torch close to
your weld after releasing the button or foot pedal, the gas flowing
during post time will cool the workpiece and will prevent it from
oxidizing while it is hot.)
n. Attach the ground cable to the front of the CT5200D/DX [photo].
