Plasma Arc Welding Disadvantages: Limitations, Costs & Risks

The high costs, specialized training needs, and safety risks of Plasma Arc Welding might surprise you. Discover the hidden challenges today.
Explore welding methods that pair with plasma cutting: TIG, Plasma Arc Welding (PAW) in melt-in or keyhole mode, and Plasma Transferred Arc (PTA) for hardfacing. Learn where each excels—thin stainless, precision tube, high-productivity joints, or wear-resistant overlays. We cover polarity (DCEN), gas choices (argon or Ar-H₂), nozzle/orifice sizing, current, travel speed, and standoff to manage penetration, taper, and distortion. See when to add filler versus autogenous passes, how pulsing improves puddle control, and why tight joint prep and torch alignment matter. Compare pros/cons with MIG and laser, spot common defects with quick fixes, and follow PPE and fume-extraction basics for consistent, high-quality results.
