105 Service Manual 6-3
Introduction
Duramax™ series machine torches are available for Powermax105 systems. The FastConnect TM quick-disconnect system
makes it easy to remove the torch for transport or to switch from one torch to the other if your applications require the
use of different torches. The torches are cooled by ambient air and do not require special cooling procedures.
This section explains how to set up your machine torch and choose the appropriate consumables for the job.
Consumable life
How often you need to change the consumables on your torch will depend on a number of factors:
• The thickness of the metal being cut.
• The average length of the cut.
• The air quality (presence of oil, moisture, or other contaminants).
• Whether you are piercing the metal or starting cuts from the edge.
• Proper torch-to-work distance when gouging or cutting with unshielded consumables.
• Proper pierce height.
• Whether you are cutting in “continuous pilot arc” mode or normal mode. Cutting with a continuous pilot arc
causes more consumable wear.
Under normal conditions, the electrode will wear out first during machine cutting. As general rule, a set of consumables
should last about 1 to 5 hours for mechanized cutting, depending upon the job.
You will find more information about proper cutting techniques in the Mechanized Cutting section.
