2-2 Duramax Retrofit Torch Operator Manual
Introduction
Duramax™ series handheld and machine retrofit torches are available for the Powermax600, Powermax800, Powermax900,
MAX42, and MAX43 systems. The torches are cooled by ambient air and do not require special cooling procedures.
This section explains how to setup your torch and choose the appropriate consumables for the job.
Consumable life
How often you need to change the consumables on your retrofit torch will depend on a number of factors:
• Thickness of the material – the thicker the material being cut, the more often consumables need to be changed.
• Average length of cut – the longer the average cut, the more often consumables need to be changed.
• Type of cutting – handheld cutting will require more consumable changes than machine cutting.
• Air quality – the presence of oil, moisture, or other contaminants will reduce consumable life.
• Piercing / edge starting – piercing the metal causes more consumable wear then starting cuts from the edge of the
metal.
• Proper torch-to-work distance – when gouging or cutting with unshielded consumables, maintaining proper torch-
to-work distance will result in better consumable life.
• Proper pierce height – maintaining proper pierce height will result in better consumable life.
• Cutting in “continuous pilot arc” mode or normal cutting mode – cutting with a continuous pilot arc causes more
consumable wear than cutting in normal cutting mode.
You will find more information about proper cutting techniques in Section 3, Operation.
