105 Service Manual
Introduction
Duramax™ series hand 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 hand 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 nozzle will wear out first when hand cutting. As general rule, a set of consumables lasts
approximately 1 to 3 hours of actual “arc on” time for hand cutting.
You will find more information about proper cutting techniques in the Hand Cutting section.
