RX WELD 12PCS #12 Tig Cups Kit with Titanium Cover - Durable TIG Cup

In this review of the RX WELD 12PCS #12 Tig Cups Kit with Titanium Cover, the bottom line is simple: this kit is aimed at TIG hobbyists and light-professional welders who need a compact set of replacement cups and consumables for DB SR and WP-series torches. Its single biggest reason to buy is the complete package of cups, gas lens diffusers and mounting O-rings plus a titanium protector, which together cover common maintenance needs and extend torch uptime without buying individual parts.

Key Features

• 180 amp max rating: Allows use on many light-duty TIG tasks where a mid-level current capacity is required, matching common workshop practice.
• Wide torch compatibility: Fits DB SR WP 9/20/25 and WP 17 18 26 torch models, making it likely to work with a range of existing TIG torches in a shop.
• Complete consumable set: Includes 2 full cups, 3 gas lens diffusers and 6 O-rings so users get immediate replacements for common wear items.
• 3/32in diffuser bore: The gas lens diffusers accept 3/32in or 2.4mm tungsten only, which is useful for welders standardized on that tungsten size.
• Titanium protector included: A titanium protector adds a durable cover to shield the cup during use and handling, increasing longevity of the set.

Who It's For

This kit suits home shop welders, hobbyists and light-commercial users who work with TIG torches listed in the compatibility and who primarily run 3/32in (2.4mm) tungsten. It is also useful for maintenance techs who prefer a small parts kit to keep their torches serviceable without ordering single items.

It is not for heavy industrial users who need very high amp cups or for welders who use different tungsten sizes regularly. Also, customers who require glass-style cups should look elsewhere because the manufacturer advises against glass walking the cup.

Pros & Cons

Pros

• Good value package: multiple consumables and a protector bundled to cover immediate replacement needs.
• Broad torch fit: listed compatibility with many DB SR and WP torch models reduces guesswork when replacing parts.
• Durable protector: titanium cover helps protect the cups during work and storage.
• Designed for common tungsten: 3/32in diffusers match a widely used tungsten size for TIG.

Cons

• Fit is mixed for some users: a few customers reported compatibility problems with WP17 torches, so expect to verify fit before committing.
• Screen durability concerns: reports indicate screens can fall out or sit crooked, suggesting quality control issues with some pieces.
