When assessing the price of a flame spray gun, you must look beyond the initial sticker price and evaluate the Total Cost of Ownership (TCO). High-quality guns typically range from $200 to $1,500 depending on whether they are manual or automated. Key factors influencing price include gas control precision, nozzle durability (tungsten carbide vs. stainless steel), and thermal efficiency. A cheaper gun often results in higher gas consumption and frequent nozzle replacements, which increases long-term operational costs. Always prioritize models with integrated flashback arrestors and adjustable flame intensity to ensure both safety and versatility.
