Introduction
Duramax™ series handheld and machine torches are available for the Powermax65 and
Powermax85 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 torch and choose the appropriate consumables for the
job.
Consumable life
How often you need to change the consumables on your Powermax65 or Powermax85 will depend
on a number of factors:
• The thickness of the metal being cut.
• The average length of the cut.
• Whether you are doing machine or hand cutting.
• 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 and the nozzle will
wear out first when hand cutting.
A general rule is that a set of consumables lasts approximately 2 to 3 hours of actual “arc on” time
for hand cutting, depending on these factors. For mechanized cutting, consumables should last
about 3 to 5 hours.
You will find more information about proper cutting techniques in Section 4,
