= Procedure: =
= Procedure: =
# Place the fume hood over the area you will be welding at
# Select electrode that is adequate for your application of material
# Grind electrode to a point. ( This gives a smaller and more directed arc)
# Insert the electrode into the collet of the torch
# Attach ground clamp to table (ensure ground contact surface is clean)
# Ensure the adjusting screw on the tank regulator is loose (Do not unscrew all the way)
# Open cylinder valve all the way
# Turn the adjusting screw (clockwise) to increase pressure to 15 CFH.
# Identify material type, and thickness that is going to be welded
# Refer to TIG welding chart for specified adjustments, specific to your application
# Clean material to remove any oxidizing and or oil residue
# Turn on the welder and adjust----------
# Hold the electrode in your dominant hand ( ensure it can move freely)
# Hold electrode about an inch away from the metal
# Using the foot pedal to control the voltage, start off with the foot pedal half way down to start a puddle on the material.
# Once a puddle is started let off the foot pedal to maintain a steady puddle without burning through the material.
# Once the puddle is formed, dab the filler rod into the puddle
# Moving along the material, walk the electrode back and forth across the puddle while dabbing the filler into the pool
# Close gas cylinder valve
# Back out adjusting screw on regulator (Do Not unscrew all the way)
# Turn off the welder
# Remove ground clamp
