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

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
