The CNC Plasma Cutting Table Operator is responsible for the safe and efficient operation of computer-numerically controlled (CNC) plasma cutting equipment to produce precision metal components in accordance with engineering drawings, work orders, and quality specifications. This position plays a critical role in maintaining production throughput, dimensional accuracy, and material utilization while adhering to all safety and quality management system (QMS) requirements.
Essential Duties & Responsibilities
Machine Setup & Operation
-
Set up and operate CNC plasma cutting table per daily work orders and router packages.
-
Load and interpret CNC programs (G-code / machine-native formats); make minor program edits as authorized.
-
Select and install correct consumables (tips, electrodes, shields, swirl rings) per material type and thickness.
-
Set plasma parameters including amperage, cut speed, pierce delay, and gas pressures.
-
Nest parts efficiently using CAM/nesting software to maximize material yield and minimize scrap.
-
Perform test cuts and verify dimensional accuracy prior to full production runs.
Quality & Inspection
-
Perform in-process inspection using calipers, squares, and tape measures to verify part dimensions.
-
Interpret engineering drawings, GD&T callouts, and cut-to-size specifications.
-
Identify, tag, and segregate nonconforming material; initiate NCR documentation as required.
-
Maintain first-article documentation and traveler sign-offs per QMS procedures.
-
Monitor cut quality indicators: dross, bevel angle, kerf width, and surface condition.
Material Handling
-
Stage raw material (plate, sheet, structural) at the machine using overhead crane, forklift, or manual handling.
-
Verify material certifications and heat/lot traceability prior to cutting.
-
Handle, label, and store finished cut parts to prevent damage and maintain part identity.
-
Return and properly store remnant material; update material inventory as applicable.
Preventive Maintenance & Housekeeping
-
Perform daily pre-shift inspections: water table level, rail cleanliness, Z-axis calibration, and consumable condition.
-
Clean slag, spatter, and water table debris per scheduled PM intervals.
-
Lubricate drive components and check drive system alignment per OEM maintenance schedule.
-
Log machine downtime, consumable usage, and maintenance actions in the maintenance log.
-
Maintain a clean, organized work area in compliance with 5S standards.
Safety
-
Follow all lockout/tagout (LOTO) procedures before performing any maintenance or consumable change.
-
Wear required PPE: safety glasses, face shield, hearing protection, steel-toed footwear, and flame-resistant clothing.
-
Monitor and maintain proper ventilation/fume extraction during cutting operations.
-
Report unsafe conditions, near misses, and incidents immediately to supervision.
Minimum Qualifications
-
High school diploma or GED required; technical/vocational training in welding, machining, or fabrication preferred.
-
Minimum 1–2 years of hands-on CNC plasma cutting experience in a manufacturing environment.
-
Demonstrated ability to read and interpret engineering drawings and material certifications.
-
Basic math skills including fractions, decimals, and measurement conversions.
-
Proficiency with common hand measuring tools (calipers, tape measure, combination square).
-
Ability to safely operate overhead crane and/or forklift (certification preferred or obtainable).
Preferred Qualifications
-
Experience with nesting software (e.g., Hypertherm ProNest, SigmaNEST, or equivalent).
-
Familiarity with Hypertherm, Lincoln Electric, or ESAB plasma cutting systems.
-
Prior experience in a defense, aerospace, or ISO 9001-certified manufacturing environment.
-
Knowledge of metal alloys: mild steel, stainless steel, aluminum, and high-strength steels.
-
Familiarity with basic G-code editing and CNC controller interfaces (Burny, Hypertherm Phoenix, or similar).
ND Defense is an Equal Opportunity Employer including disability and veteran.
