Application
This unit describes the performance outcomes required to set up an oxyacetylene plant, follow safety requirements, adjust gauges to recommended working pressures, and conduct thermal heating and cutting. It involves preparing for the task, identifying and adjusting flame appropriate to thermal heating and cutting requirements, selecting and using suitable personal protective equipment (PPE), performing oxyacetylene thermal heating and cutting to given instructions, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

oxyacetylene flame identification and applications, including:
natural
carburising
oxidising
maintenance requirements of oxyacetylene equipment, including checking for oxyacetylene gas leaks from gauges, fittings and hoses
methods, techniques and procedures for oxyacetylene thermal heating and cutting
procedures for protecting vehicle and components during oxyacetylene thermal heating and cutting work
procedures for final inspection of oxyacetylene thermal heating and cutting work.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to having used oxyacetylene thermal heating and cutting on vehicle body sections, e.g. work orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
PPE required to conduct oxyacetylene thermal heating and cutting
oxyacetylene plant
three different vehicle body sections requiring thermal heating and cutting
oxyacetylene safety equipment and operating instructions
tools, equipment and materials appropriate for carrying out oxyacetylene thermal heating and cutting.
