Plasma cutting torch Duramax® Lock

roboticfor machinesmanual

Overview: Duramax® Lock torches have the ruggedness and reliability of the original Duramax torches. They support handheld and mechanized cutting of a wide range of metal thicknesses and offer enhanced gouging and marking capabilities. Duramax Lock torches are available with an extensive array of specialty consumable options for applications such as gouging, fine feature cutting, extended reach cutting, and flush cutting.

Features:

• Trigger lockout switch helps prevent accidental firing.
• Torch disable switch feature allows faster, easier changeout of consumables.
• SpringStart™ electrode technology for more reliable arc-starting (eliminates moving parts in the torch).

Applications:

• Drag cutting — For dragging the torch directly across the work piece.
• Extended reach cutting — For cutting at extended reach to access difficult areas.
• Extended reach gouging — For improved visibility and accessibility in confined spaces.
• Fine feature cutting — For cutting small, detailed features.
• Flush cutting — For cutting flush to base materials.
• Marking — For scoring and 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 and deep gouge profiles.
• Mechanized cutting — For portable automation and table cutting.
• Precision gouging — For spot and tack weld removal at very low output currents (<25 A).

Benefits:

• More reliable arc-starting via SpringStart™ electrode technology.
• Hand torches: Duramax® Lock 75° and 15° models suited for gouging, fine feature cutting, extended reach cutting, and flush cutting; 75° ergonomic design for normal cutting; 15° directs heat away from operator for heavy gouging and overhead or hard-to-reach cutting.
• Machine jobs: Duramax Lock full-length machine torch compatible with a wide variety of CNC cutting tables, track cutters, and pipe-cutters.
