Plasma cutting torch Duramax™

manualfor machines

Overview
Duramax™ retrofit torches can give your Powermax1000, 1250 or 1650 system new life with enhanced performance and reliability. Easy Torch Removal (ETR) connections come standard, making installation, literally, a snap.

Available styles

• 75° and 15° handheld
• Full-length machine
• Mini machine

Applications

• Drag cutting – For dragging the torch directly across the work piece.
• Fine feature cutting – Fine-feature profiling and detail cutting.
• Flush cutting – Cutting flush to surfaces.
• Marking – For scoring, indicating part identification, hole or weld locations.
• Max control gouging – For precise metal removal, shallower gouge profiles and light metal washing.
• Max removal gouging – For aggressive metal removal, deep gouge profiles, and extreme metal washing.
• Mechanized cutting – For portable automation and table cutting.
• Precision gouging – For spot and tack weld removal at very low output current (<25 A).

Benefits

• More consumable life – Conical Flow™ nozzle and Spring electrode give you up to 30% reduction in consumable costs over T-style torches (when compared with standard T60/T80/T100 torches and/or consumables).
• More reliable arc-starting – SpringStart™ electrode technology eliminates moving parts in the torch for more reliable arc-starting.
• More durable – Proprietary, fiber-reinforced torch handle is 5 times more impact resistant and 20% more heat resistant than T-style torches.
• CopperPlus™ long life electrodes – Provide dramatically longer service life than standard consumables when cutting metal 1/2" and under.
