Torch vs. Plasma Cutter

• Comes down to initial cost versus long-term cost
• Plasma cutters - consumables cost $20 for 5 new electrodes and nozzle heads
  • Electrodes are rated for 45 minutes to 60 minutes for 1/2" steel
  • More expensive versions state they last 4 times longer - are heavier and have better temperature control
  • For anything above 1 inch, torch is better
