45 Service Manual
Introduction
Both the T45v hand torch and the T45m machine torch are available for the Powermax45. The torch FastConnect™
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 both torches.
This section explains how to set up your torch and choose the appropriate consumables for the job.
Consumable life
How often you will need to change the consumables on your Powermax45 will depend on a number of factors:
• The thickness of the metal being cut.
• The length of the average 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.
• Which consumables you are using. The T30v (Powermax30) 30 amp consumables will have a shorter life when
used on the T45v. However, they provide optimum cut quality for certain applications.
Under normal conditions, the electrode will wear out first during machine cutting, and the nozzle will wear out first when
hand cutting.
A good rule of thumb is that a set of consumables will last approximately 1 to 2 hours of actual “arc on” time for hand
cutting, depending on these factors. For cutting with a machine torch, consumables may last up to 3 to 5 hours.
You will find more information about proper cutting techniques in the Operation section.
