Thermacut T-11932 ohmic retaining cap 105A for Hypertherm Duramax machine torches

Thermacut T-11932 is the ohmic version of the 105A retaining cap for Duramax torches on Powermax 105 systems. It holds the front-end consumables in place, and its wire terminal lets a cutting table sense the plate surface.

What "ohmic" means

Some CNC tables use the torch to find the top of the plate electrically, then set the pierce and cut heights from that reading. Those tables need a retaining cap with a terminal for the sensing wire. That is an ohmic cap. If your table doesn't use ohmic sensing, you don't need one.

Choose the right retaining cap

• 105A, standard: T-11422 – Retaining Cap 105A
• 105A, ohmic: T-11932 (this part)
• Up to 85A, standard: T-11423 – Retaining Cap 45/65/85A
• Up to 85A, ohmic: T-11931 – Retaining Cap Ohmic 45/65/85A

Thermacut's chart shows a different retaining cap for 105A, so don't swap in an 85A cap.
