meeting was held at Tool Craft, once again we give a hearty round of thanks to
Bob Sanders and his crew.
Rick Sparber started the meeting with a discussion of welding safety
concentration on what you are doing.

ventilation or fumes from welding
from sparks, radiation, etc ("it's hard to concentrate with your hair
Wear appropriate clothing
not wear synthetic materials while welding

your skin from radiation burns Long sleeves recommended
your eyes! Your webmaster can vouch for this personally.
I tried to do a "quicky" repair under a piece of equipment where
I could not fit the helmet and used a pair of safety glasses that had
welding tinted lenses. The light leakage around the sides caused
painful radiation burns on both eyes. Several days passed before it
stopped hurting. You have been warned!
safety glasses under the welding helmut
your ears from noises Grinding goes with welding and is very noisy
wear tennis shoes. They burn!
auto darkening helmut is recommended for all kinds of welding
Bart Hull discussed welding aluminum with TIG
offers manuals for all their products on the Miller
Welding web site
magnifying lens inside the helmut makes seeing the pool easier
gas lens on the welding tip extends the distance the electrode can be
extended out from the torch to reach into tight spots
is the cover gas for up to ¼" aluminum plate
is the cover gas for alumninum plate over ¼" thick
gas is used to increase heat penetration in aluminum plus avoid oxidation
of the metal
When checking for cover gas flow, do not put the torch up to your
ear. The high frequency arc from the torch to your ear can really
hurt. Does Bart know this because of personal experience?
welders can be either AC or DC operation. AC is recommended for
prep and cleaning is critical for a good aluminum weld.
Dale Schmidt discussed TIG welding other metals
ti[ shapes differ for aluminum and other metals. Aluminum uses a
ball shape tip. Other metals use a pointed tip
the tip with all grinding marks parallel ti the long axis of the tungsten
electrode. This keeps the arc from swirling
welding is used on material less than ½" thick. It takes too
much power to TIG weld thicker metals
welding does not use gaps between but weld pieces.
into a comfortable position before striking the arc. Rest the
electrode tip on the spot where the weld is to be started. Adjust
you body position as needed to get comfortable. Then raise the tip
up and hit the pedal to strike the arc
Bart demonstrated aluminum welding and then several club members got a chance to
try their hand under expert tutors
Sparber gave Safety Discussion, shown holding appropriate shirt. David
