Tweco 1046-2258 Smoke Master Conductor Tube 450A 60 Degree

Product Description

The TWECO 1046-2258 is a Smoke Master conductor tube designed for MIG welding applications requiring integrated fume extraction at the weld zone. Rated at 450 amps, it features a powder coat finish and a 60-degree angle configuration. The metal outer jacket is standard on this tube, providing durability in demanding shop and fabrication environments. Back-end threads are O.D. M12 x 1.5-6G and front-end threads are I.D. M11 x 1.5-6H. Licensed welding professionals and fabrication technicians install this component as part of a smoke extraction welding gun assembly.

This conductor tube is suited for semi-automatic MIG welding setups where fume control is a priority. It is designed to remove up to 90% of smoke from the weld zone, making it appropriate for enclosed fabrication shops, manufacturing facilities, and job sites where air quality standards must be maintained. The 60-degree angle suits welding positions where gun geometry needs to be matched to joint access and operator ergonomics.
