What’s Included in This Kit

The ARCCAPTAIN kit covers the core consumables for WP-17, WP-18, and WP-26 torches:

• 1x Alumina Nozzle — Ceramic cup for shielding gas flow

• 2x Collets — Electrode holders (standard sizes for 1/16″ and 3/32″ tungsten)

• 2x Back Caps — Torch body connectors

• 2x Gas Lenses — Improved gas coverage and shielding

• 2x Ceramic Cups — Replacement nozzles for wear

• 2x Insulating Bushings — Electrical isolation components

This multi-pack approach means you have spares on hand, reducing downtime when a part fails mid-job.

Who Should Buy This Kit

This kit is ideal for:

• Hobby and shop welders stepping up from single-piece replacements to a complete consumables set

• TIG welders running WP-17/18/26 torches who want to avoid emergency supply runs

• Fabricators and instructors who need backup parts for multiple torches or training setups

• Budget-conscious shops looking for a multipack at a reasonable price point

ARCCAPTAIN 11Pcs TIG Welding Torch Consumables Kit Collets Alumina Ceramic Cups for WP-17/18/26

Performance & Use

What to Compare Before You Buy

• Torch Compatibility — Verify your torch model (WP-17, WP-18, or WP-26); this kit is NOT compatible with WP-9 or larger industrial torches

• Tungsten Size — Confirm whether you run 1/16″, 3/32″, or mixed tungsten sizes; collet sizing matters for arc stability

• Gas Lens vs. Standard Cup — Gas lenses improve shielding in drafty environments; standard cups work fine for bench work

• Material Grade — Alumina cups are standard; some shops prefer ceramic for specific applications

• Quantity — This is an 11-piece set; if you run multiple torches daily, consider buying two kits

Comparable Amazon Picks (Optional)

•  CK Worldwide TIG Torch Consumables Kit (WP-17/18/26)  — Premium option with higher-grade ceramics; typically $45–$65

•  Lotos TIG Torch Accessory Kit (WP-17/18/26)  — Mid-range alternative; $25–$35

Installation & Maintenance

Swapping consumables is straightforward:

1. Cool the torch — Let it sit for 2–3 minutes after your last weld

2. Unscrew the back cap — Use a 7/16″ or 1/2″ wrench; don’t force it

3. Remove the old collet and cup — They slide out together

4. Insert new collet and cup — Align the collet with the torch body; it should sit flush

5. Reattach the back cap — Hand-tighten, then snug with a wrench; over-tightening can crack the collet

Maintenance tip: Clean the torch body and collet threads every 20–30 hours of welding to prevent carbon buildup and stuck parts.

Durability & Lifespan

Consumables wear at different rates depending on amperage, duty cycle, and shielding gas:

• Collets — 40–80 hours of active welding before replacement

• Ceramic cups — 30–60 hours; cracks indicate replacement time

• Gas lenses — 50–100 hours; clogging reduces gas coverage

• Back caps — 100+ hours; rarely need replacement unless cross-threaded

At $25–$35 for this 11-piece kit, you’re looking at roughly $2–$3 per consumable part, making it a cost-effective backup supply.

Safety Notes

• Always wear welding gloves when handling hot torches or consumables

• Ensure your torch is cool before disassembly

• Check gas lens alignment; misaligned lenses can cause poor shielding and porosity

• Use only argon or argon/CO₂ blends with this torch; check your machine’s gas compatibility

When to Replace This Kit’s Parts

Replace consumables when you notice:

• Erratic arc — Worn collet or misaligned cup

• Visible cracks or pitting on ceramic cups

• Gas coverage loss — Clogged gas lens or damaged nozzle

• Difficulty inserting tungsten — Worn collet
