The Fupa 12 Ceramic Kit takes TIG welding performance to the next level. This professional-grade kit includes two robust ceramic cups and a spare diffuser, offering the same exceptional performance as the glass version but with enhanced durability. Designed specifically for 3/32 - 2.4 mm tungsten size, these cups seamlessly thread onto 45V44 or 17 torch mount Kit setups, eliminating the need for O-rings. The system can handle up to 180 amps non-continuous operation and is optimized for DC applications. The specialized diffuser system features a dual-layer screen design with a precise gap that's crucial for optimal performance. Installation requires careful attention - the cupped side should be inserted first, and proper sealing is essential for best results. Made in the USA, this kit brings together precision engineering and practical functionality. Note that the diffusers are designed exclusively for Furickcup brand cups and should be considered consumable parts that may need periodic replacement to maintain peak performance.
