We regularly get calls from customers who may have begun cutting on an HPR system but now have upgraded or purchased an HPRXD and are struggling with torch leaks, cut quality issues, or consumable life. One potential root cause in these instances is incorrect torch assembly. We have found customers often do not realize consumables in the HPRXD torches need to be assembled in a slightly different way.
What is the difference? The image below outlines consumable installation for an HPR system as shown in the HPR260 manual.

Now compare the above image with the image below. This image shows how to install consumables in today’s HPRXD systems. Notice the difference in the shield installation. Before, it was fine to put the shield into the shield cap, and then screw both down onto the rest of the torch.

However, with the HPRXD torch it is important to install the shield first onto the nozzle retaining cap, then place the shield cap on and tighten that down. If this isn’t done correctly you wind up with a pinched or misaligned o-ring, which can cause your torch to leak or shorten consumable life and impact cut quality.
Ensuring this change is better known will ultimately save you time, money, and frustration. We are all about process reminders which are preventive, and hope you find value in these tips too! |
