cillated in a gure 8 pattern. This will require a fore-
hand grip typically, and a good bit of motion of your
forearm to accomplish. The ller metal should be
moved from side to side to provide an evenly lled
puddle under the Tungsten. This method requires
much practice and effort, but yields beautiful welds
when performed correctly. If you cannot see the pud-
dle or your helmet flashes (auto darkening types), you
need to change your settings or obtain a welding hel-
met rated for 5 amp TIG use. Set delay to long and
sensitivity to maximum (or the lowest Amp setting).
Practice feeding the ller wire without actually weld-
ing. Manipulating the wire takes practice and concen-
tration at rst. The wire should be held so that a flick-
ing motion of two ngers and the thumb can propel
the rod forward into the puddle without loosing grip
on the ller rod. The rod should rest on the two n-
gers furthest from the thumb, while the index and
middle nger grasp the rod with the thumb propelling
it forward. Other rod manipulation variations may be
used, but the key is to develop a comfortable, natural
movement that is regular and consistent. If feeding
difculty is encountered, there are some feeding de-
vices that reduce the effort to feed the ller wire and
smooth out the feeding process. Do not let feeding
the ller wire hold up the learning process. There are
numerous accounts of welders making home-made
jigs or devices that help feed the TIG rod smoothly.
Make sure you have gloves that offer protection with-
out compromising dexterity. With a proper tting TIG
glove, you should be still able to pick the ller wire up
from the table top with your ngers.
There are a lot of hurdles to becoming a procient TIG
welder. But if you will practice when you are not
tired, and when you are comfortable in your sur-
roundings, you will generally obtain better results than
if you would if you are too tired, or over-heated.
