冷卻管

Swapped out the old one and this fit the Trafimet Z series torch perfectly, no fuss. The threads were clean and it seated snug right away, so I’m back to welding without worrying about the heat buildup. Just what I needed to keep things running cool.

The fit on my Z series torch is spot-on, and the tube keeps the whole setup running cool even during longer welding stretches. Swapped it out in a few minutes and haven't had a single overheating hiccup since.

Finally got this replacement for my aging Z series torch and the heat dissipation is noticeably better during long cuts. It stopped the handle from getting too hot to hold after 20 minutes of use. Simple fix that works exactly as intended.
