5. Pneumatic Systems
Compressed air running valves, actuators, and tools. Quick, clean, and wonderfully modular—if leaks and moisture don’t run wild.
Why It's Important
Pneumatics power countless motions and clamps. When tuned, they’re responsive and cheap to keep running.
How to Improve Pneumatic Systems Skills
Stop the bleed: Do leak surveys, fix fittings, and set standard torque—compressed air is expensive.
Dry and clean: Maintain dryers, monitor dew point, replace filters, and drain receivers.
Right-size everything: Tubing, valves, and actuators matched to flow and speed needs.
Lubricate wisely: Use manufacturer-recommended lubricants or run oil-free where required.
Watch the pressure: Regulate locally, add soft starts, and use quick exhausts where motion demands it.
Instrument and trend: Flow meters and pressure transducers pay off in uptime and energy savings.

6. Welding Techniques
SMAW, GMAW/MIG, GTAW/TIG, FCAW—choose the method, match the filler, control the heat, and make it hold.
Why It's Important
Repairs stick when welds are sound. Poor technique warps parts, cracks later, and invites rework.
How to Improve Welding Techniques Skills
Dial in settings: Voltage, amperage, wire feed, gas flow—tune for material thickness and joint design.
Prep like a pro: Clean joints, proper fit-up, correct bevels, and gap control reduce defects.
Control the puddle: Practice torch angle, stick-out, travel speed, and weave—muscle memory matters.
Mind the metallurgy: Watch heat-affected zones, preheat where needed, and avoid distortion with sequencing and fixturing.
Follow procedures: Use WPS where required; qualify process, procedure, and people for critical work.
Protect yourself: Proper PPE, ventilation, and housekeeping keep you sharp—and safe.

7. CNC Machinery
Computer-controlled mills, lathes, routers, and grinders shaping with microns in mind. Your job: keep them accurate, repeatable, and available.
Why It's Important
Precision equals profit. Stable CNCs cut scrap, speed changeovers, and keep quality tight.
How to Improve CNC Machinery Skills
Maintain on cadence: Clean way covers, lubricate axes, check backlash, and verify coolant concentration.
Keep software fresh: Controller firmware, post processors, and CAM libraries up to date.
Calibrate regularly: Ballbar tests, laser interferometry, spindle probe checks, and fixture verification.
