High Quality OEM TIG18 Welding Torch with Replaceable Switch 0.5-4mm Electrode Size for Metal Fabrication

We're seeing a lot of interest in the TIG18 lately, especially for setups where you need a gas-cooled torch that can handle up to 320A DC—which is actually plenty for most industiral work, though you'll want to keep an eye on duty cycle at higher amps since it's 180A DC at 35%.

The electrode range here is 0.5mm to 4mm, so you're covered for pretty much everything form thin sheet metal up to heavier plate, and the balanced pressure design gives stable arc that's better than cheaper nozzles for consistent bead width.

Most buyers we deal with—automotive repair shops and light fabrication houses especially—tend to stick with the 8M length for maneuverability around frames, though the 4M is easier to manage if you're working on smaller benches or in confined spaces.

Lead time is usually about 20 working days or so for bulk orders, and we've got a 100-unit MOQ on the replacement switches if that's what you're after—those are interchangeable with other standard TIG18 bodies, but you'll want to confirm the pin-out on your existing torch first.

One thing people don't always ask about upfront is that the switch is fully sealed, which makes a real difference when you're welding in dusty environments; you don't get that intermittent trigger failure that plagues open-contact designs.

Anyway, typical bulk pricing runs around $18-$24 per piece on the 8M version depending on quantiy, and we ship with COA and SDS for customs clearance—just note that the duty cycle drops significantly under AC, so it's not your best bet for continuous aluminun work at full stick-out.
