I'm not sure what that other person is saying. Tungsten inert gas (tig) welding process is for welding metals such as aluminum, stainless steel, and different types of alloys. **Q: Does this machine have a foot pedal available for it and how much .** A: this machine does not need a foot pedal. **Q: Need parts for 3 1n 1 plasms cuttertig/mma?** A: The tig torch on most Chinese ct312 units is a wp-17 unit. You can find parts for these torches all over the internet. The tungsten electrodes are available at every tool retailer in America. As for the plasma cutter torch, it depends on which unit you have. If you have a standard unit, you most likely have a pt31 torch. If you have a ct312 PILOT ARC unit, you most likely have a wsd-60p torch. Again parts widely available on the net. Hope this helps. **Q: What scfm is required for plasma cutter?** A: Under 40 PSI. ## Frequently Bought Together - Plasma Cutter TIG Welder (Pulse) Stick Welder - CT418 3 in 1 Combo Welding Machine, 180A Pulse TIG/Arc Welding, 40A Plasma Cutting, 110/220V Dual Voltage Digital Display Portable Welder Machine - RIVERWELD P-80 Plasma Cutter Roller Guide Wheel Spacer Circle Compass Stand Off One Screw Positioning Fit Pilot Arc Starting --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/519258600-tig-mma-air-plasma-cutter-tosense-ct312-3-in-1](https://www.desertcart.us/products/519258600-tig-mma-air-plasma-cutter-tosense-ct312-3-in-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-15*
