Monster™ Cup Best Practices, Set-Up Tips, Do's & Don'ts!

  • The Monster™ Cup works best with Arc-Zone's high-quality gas lens collet bodies
  • The Monster™ Cup is designed for Argon flow rates between 15-30 CFH (cubic feet hour)
  • Do Not Exceed 175 amps for extended periods of time!
  • The Monster™ Cup is Not designed for welding with AC current!
  • Minimum tungsten stickout of 3/4" (19mm) -- Shorter stickout may result in damage to the screen stack
  • Use a medium or short back cap ONLY. (Long back caps are known to trap atmosphere in the top of the cap)
  • Do not adjust the positioning, or modify the Screen Stack in any way

Monster™ nozzles are designed for precision TIG welding applications where increased shield gas coverage and tungsten stickout are needed. They are not designed for heavy-industrial pipe welding applications. 

Arc-Zone does not make any claims or guarantees of weld-quality improvements, or level of shield gas coverage. Results may vary, due to: weld station set-up, material preparation, gas quality, gas flow rates, flow meter type, gas hose material, welding machine, TIG torch, operator’s torch handling technique, etc.

Compatible with popular TIG torch models including: A125 (WP-9), W250 (WP-20), W280 (CS310) and CK 2 Series.

I use the #12 Monster Nozzle on my CS310 Torch. At first I was skeptical.
Now after using it for about two months I am a Believer!!!
I always have my Arc-Time Sky Blue Hybrid Tungsten stick out at 3/4" and it just works.
The Weld finish always looks Amazing!!
