  1. Welding and Oxy – Acetylene Cutting Equipment and Safety

  2. Objectives • Identify equipment used in welding and oxy- acetylene cutting. • Use proper safety procedures when welding and oxy- acetylene cutting. • Identify safety equipment used in welding and oxy- acetylene.

  3. Welding Equipment • Power source • 110 unit • 220 unit • 440 unit • Diesel unit

  4. Oxy- Acetylene Equipment • Torch • Regulator • Hoses • Striker • Tip cleaner

  5. Long sleeve shirt Long pants Foot wear Safety glasses Gloves Helmet Safety Equipment

  6. Welding Safety • Always wear proper clothes when welding • Place ground lead on material before turning machine on. • Check cables for cuts in the insulation. • Never stand in water when welding. • Never use gloves to pick up hot material. • Never weld near flammable objects.

  7. Oxy- Acetylene Safety • Make sure regulators are tight. • Never use oily rags around cylinders and regulators. • Check hoses for leaks before lighting the torch. • Make sure regulators are at proper settings. 15 psi max. acetylene 40 psi max. oxygen

  8. Continued • Make sure mixing knob is off before lighting torch. • Light acetylene first then mix oxygen. • Do not pick up material with gloves after it is cut. • Cut off cylinders when through cutting.

  9. Review • Why does one wear a long sleeve shirt when welding? • How high can the acetylene regulator be set? • When must one use safety when cutting or welding?
