Clock Hours: 30

Delivery Mode
on-ground

Course Description:
The goal of this course is to gain knowledge of cutting theory and practices of Oxy-Fuel and handheld Plasma-Arc cutting. This is accomplished through related bookwork, hands-on instruction and work based competencies

Student Learning Outcomes:
Students will be able to demonstrate knowledge of: 

  • Describe the use of Oxy-Fuel cutting processes 

  • Discuss the materials that can effectively be cut with Oxy-Fuel processes 

  • Describe proper eyewear for Oxy-Fuel cutting processes 

  • Using a chart, select the proper size cutting torch tip for a given application 

  • Demonstrate how to properly set up a cutting torch 

  • Demonstrate the proper method of cleaning a cutting torch tip 

  • Demonstrate how to safely light and adjust an Oxy-fuel cutting torch flame 

  • Explain what actions should be taken to ensure a smooth cut is made, using the Oxy 

Fuel process 

  • Describe how to accurately perform a straight line cut 

  • Demonstrate how to correctly set working gas pressure on the regulators 

  • Explain the process of cutting, and the role of the gas mixture in producing the 

necessary heat to displace the metal 

  • Explain how examining the cut surface can help troubleshoot issues with incorrect 

preheat, cutting speeds and oxygen pressure 

  • Evaluate the results of preheat, speed and pressure after making a cut 

  • Describe soft slag and hard slag and the causes for both 

  • Describe how a fence or guide can be used to perform more accurate cutting 

  • Demonstrate a straight cut in a flat position in various material thicknesses 

  • Demonstrate how to perform a hole perforation and cutting circles/shapes 

  • Describe methods of controlling heat distortion 

  • Demonstrate a straight line cut in the vertical and overhead positions 

  • Describe plasma arc cutting and how it works 

  • Explain the setup of a plasma torch 

  • List the advantages of plasma arc cutting compared to oxy-flame cutting 

  • Demonstrate cutting a straight cut using a hand held plasma torch, repeat for circles 

and shapes, with and with a guide/fence.
