WARNINg! TO pREVENT SERIOUS INJURy:
protective gear must be worn when using the
Welder; minimum shade number 10 full face shield
(or welding mask), ear protection, welding gloves,
sleeves and apron, NIOSH-approved respirator,
and fire resistant work clothes without pockets
should be worn when welding. Light from the
arc can cause permanent damage to the eyes
and skin. do not breathe arc fumes.

10. Hold TIG Torch in one gloved hand and the TIG
Rod (sold separately) in other gloved hand.
NOTE: Maintain a constant distance between the
Tungsten Electrode and the workpiece: between
1 and 1.5 times the diameter of the Electrode.
11. When welding puddle is hot enough, tilt torch
backward about 10-15 degrees from vertical and
move it back slightly. Add TIG Rod material as
needed to the front end of the weld puddle.
12. Alternate between pushing the torch/weld
puddle and adding the TIG Rod material.

is advanced, but do not remove it from the gas shield.
This prevents oxidation from contaminating the weld.

keep Torch on weld puddle until gas flow ends.
14. Set TIG Torch down on nonconductive,
nonflammable surface away from
any grounded objects.
