Machine Torch Setup
Introduction
Duramax Hyamp series machine torches are available for this system. The FastConnect 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.
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 3 hours for 125 A mechanized cutting, depending on the job. Cutting at lower amperages may
yield longer consumable life.
You will find more information about proper cutting techniques in Mechanized Cutting on page 97.
