Product identity

Miller Enterprises 45V28 gas lenses are copper and brass consumables for TIG welding torches. Each pack contains two pieces sized at 5/32 inch (4.0 mm). They fit A-150, A-200, W-350 and W-410 series torches. Welders who need shield-gas column stability for critical joints will use these.

Sustained performance

The copper and brass body resists heat buildup during long welding runs better than standard collet bodies. Gas flows evenly through the lens screen, keeping the argon shield intact on stainless steel or aluminium. The two-pack lets you keep a spare ready when the current piece wears out.

Thermals noise power

Copper and brass conduct heat away from the torch head, helping the handle stay cooler during extended passes. No moving parts mean silent operation. Power draw is whatever the welding machine delivers; the lens itself adds no electrical load. Proposition 65 warnings apply for California users.
