Welding Equipment UVU CRT 2009

Welder  The welder used in the Spanish Fork High Collision Repair Shop is a 135 amp wire feed Metal Inert Gas (MIG) welder. UVU CRT 2009

Shielding Gas  A 75% Argon 25% Carbon Dioxide (C25) gas is used to protect the weld puddle from contaminates.  This mix gives a quality flat weld that is beneficial for collision work. UVU CRT 2009

Gas Regulator  This is the pressurized gas regulator.  The optimum flow setting is 17 cubic feet/minute. UVU CRT 2009

Inside the Welder .023 Continuous Wire Spool.  Leads to reverse the weld polarity.  Wire Tension Control UVU CRT 2009

Welding Gun Assembly Gas Nozzle Contact Tip.023 Wire Liner Gas Diffuser UVU CRT 2009

Contact Tip  Wire feeds through the contact tip which provides the electrical contact.  The contact tip is a wear item that should be replaced occasionally. UVU CRT 2009

Gas Nozzle  Used to focus the shielding gas over the weld puddle. UVU CRT 2009

Wire Liner  The wire feeds through the liner to the contact tip.  The liner is also a wear item that should be replaced when the wire feed is irregular. UVU CRT 2009

Welding Pliers  Combination style pliers for cutting welding wire and tightening contact tips etc. UVU CRT 2009

Clecos  Reusable blind rivet system used to secure overlapping panels. UVU CRT 2009

Air Drill  Drill 1/8” holes for the Clecos.  Drill 5/16” holes for spot welds UVU CRT 2009

Cut Off Tool  Abrasive disc used to cut sheet metal panels. UVU CRT 2009

Tin Snips  Aviation tin snips allow right and left hand cuts without deforming the metal. UVU CRT 2009

Roloc Angle Grinder  Roloc discs are designed to remove surface contaminates from the metal without thinning the metal. UVU CRT 2009

Panel Crimper  Used to crimp the edge of the panel for an offset lap weld. UVU CRT 2009

Vice Grips  Holding and securing panels for welding. UVU CRT 2009

Metal Hole Punch  5/16” Metal Hole Punch.  Used for making holes in sheet metal for plug welds. UVU CRT 2009

Welding Tools  These are the basic tools that will be used to perform the welds required for completion of the welding and cutting steel module.  We will discuss there correct use in the lab portion of the class. UVU CRT 2009
