Replace first
Cracked or contaminated cups are the fastest visual check when gas coverage is poor.
Loose tungsten usually points to the wrong collet size or a worn collet before the whole torch is bad.
If the arc is unstable or gas coverage is poor, confirm the front-end style before buying parts.
Verify fitment
Confirm WP-9, WP-9V, WP-9F, or WP-9FV before ordering handles or valve parts.
Standard, gas lens, and large-diameter gas lens setups require different parts.
Amazon links are optional buying references only. Unverified matches stay blocked.
