General Information 

 

 

Thank you and congratulations on purchasing an HTP MicroCut 875SC. With many  

welding and cutting equipment options available on the market today, we appreciate your  

purchase, as well as the confidence you put into HTP through purchasing one of our  
products. 

 

The versatile MicroCut 875SC works with CNC plasma cutting tables—a first for HTP— 

with the addition of our optional CNC interface and 20’ machine torch. However, you can 
also operate the MicroCut 875SC manually with a 20’ hand torch. If you purchased the 20’ 

hand torch, you can always upgrade your machine to meet CNC plasma cutting  
table compatibility at a later date. As an added bonus, the hand torch and machine torch 

utilize the same consumables, apart from the shield cap, so you only need to keep on-hand 
and track-of a single style of replacement parts. 

 

We hope you enjoy working with your new plasma cutting machine! If you need help  

setting up or operating your plasma cutter, at any time, please feel free to contact us.
