I bought 2 (2 packs) to have a few extras, this even with shipping a total of 4 of these tips, was cheaper than 1 at the welding supply (and it woudn't have been an OEM Miller either). My number was barely readable on the old one from so much use, but a couple of guesses on the last digit got me to this. It was a perfect fit on my Millermatic 250, which is an older machine, but I wouldn't trade it for a new one. I will be buying more from WeldingCity . They just won me over as a dedicated customer. ### ⭐⭐⭐⭐⭐ Good value *by G***I on January 1, 2021* Bought these for my Hobart welder.They fit great, and work great. ### ⭐⭐⭐⭐ Four Stars *by G***R on February 15, 2015* Good product at good price, shipping was good and on time. --- ## 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.tn/products/9961997-weldingcity-2-pk-mig-welding-gun-contact-tip-adapter-gas](https://www.desertcart.tn/products/9961997-weldingcity-2-pk-mig-welding-gun-contact-tip-adapter-gas) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-12*
