Lincoln Electric K1782-2 TIG Torch 150A Air-Cooled
The Lincoln Electric K1782-2 Magnum TIG torch delivers 150 amps maximum current with a 60 percent duty cycle for light-duty GTAW work. Its air-cooled design and rigid neck suit workshop and field repairs where a compact, durable torch is required. The torch accepts electrodes up to 5/32 inch and fits Lincoln-compatible C300 style connections.
Welders needing a light-duty air-cooled torch
This torch suits fabricators and maintenance technicians who need a comfortable knurled handle for extended use in confined spaces. The rigid neck and molded lip provide stable control for precision joints. It is not for operators requiring a flexible neck, water-cooled cooling, or a duty cycle above 60 percent for continuous high-amperage production runs.
150A maximum current with 60 percent duty cycle
The 150 amp rating at 60 percent duty cycle defines the torch’s continuous welding capacity before cooling pauses are needed. Exceeding this limit risks overheating the air-cooled head and shortening consumable life. Match the torch to your power source output and typical joint duration to avoid thermal overload.

Questions about this item
How do I install the K1782-2 torch onto a Lincoln C300 power source?
Connect the Lincoln-style power and gas fittings to the C300; the step many miss is fully tightening both connections before welding to prevent gas leaks.
What consumables will need replacement on this 150 A air-cooled torch?
The collet, collet body, ceramic cup and tungsten electrode wear out; maximum electrode diameter is 5/32 in.
At what point does the 60 % duty cycle limit continuous welding at 150 A?
At 150 A you can weld for six minutes out of every ten; exceeding this triggers thermal protection and stops output.
