Introducing the new  

XLR-8 Drive System

In the mid 1940s, the aviation world realized that the technological evolution of piston/propeller powered aircraft had reached its apex.  Military aircraft at the time had reached 400mph, and in a practical sense, could go no faster.  Since the existing technology could go no further, a technological revolution was called for to move to the next speed plateau.  This was the time when jet technology was introduced. 

Dynatorch has always been on the leading edge of technology.  We have produced an exceptional drive system tailored to plasma and oxy-fuel cutting, that we believe is the best in the industry.  For the last 10 years we have constantly improved our system, with the addition of features and changes to make the system even more efficient.  We realize that there are many things that we would like to introduce to the plasma cutting world, however, our present technology does not permit additional evolution.  Like propeller driven aircraft in the 1940s, it is time for a technological revolution. 

With the above in mind, Dynatorch is proud to announce the XLR-8 drive system.  Designed expressly and exclusively for plasma and oxy-fuel cutting applications. 

What is different and why it is better

  1.     The XLR-8 utilizes servo motors that are twice as powerful as our current servo motors.  We are constantly being asked to utilize our drive systems on larger and heavier gantries.  These applications require a drive system with more power, so speed on the larger gantries is not sacrificed. 

2.     The XLR-8 system uses encoders capable of 10,000 pulses per revolution, giving the user incredible motion resolution.  More resolution means better and more accurate torch positioning.

3.     Our current drive system was limited on communications speeds between the personal computer and motors.  Communications speed controls the amount of information necessary to accurately cut an object.  An extreme example of this limitation might be cutting a very small circle and having the cutting result look like the shape of a stop sign.  The XLR-8 communication system can deliver significantly more cutting information to the motors, resulting in more detailed and accurate cuts.

 4.     Smoothness in cutting is a goal we always strive for.  It’s obvious that the smoother the servo motor rotation is, the smoother the resulting cut will be.  The XLR-8 utilizes sinusoidal commutation, and  is the preferred method of operation if smoothness is desired.

 5.     The plasma cutting environment is typically dirty and rife with electrical interference.  The XLR-8 uses components with exceptional reliability that will give many years of quality service.  

To summarize:  The new Dynatorch  XLR-8 drive system with integrated arc voltage torch height control is more powerful, faster, smoother and is capable of more accurate cutting than our previous systems or competition.
