Module 3: Machine Operation & Setup¶

Overview¶

This module provides hands-on procedural instruction for setting up and preparing a plasma cutting system for operation. Students will perform gas pressure verification, consumable selection and inspection, ground clamp configuration, and standoff distance verification. By the end of this module, students will be able to independently set up a plasma system and perform test cuts with proper parameters.

Learning Objectives¶

Perform gas pressure verification and adjustment using a regulator
Select correct consumables by amperage rating
Inspect consumables for damage and wear
Properly configure and test ground clamp connections
Verify and maintain standoff distance during cutting
Perform startup and shutdown procedures safely
