Air Cooled WP-27 TIG Welding Torch 350A Heavy Duty Industrial Grade 60% Duty

Air Cooled WP-27 TIG Welding Torch 350A Heavy Duty Industrial Grade 60% Duty

The WP-27 is a large, air-cooled TIG welding torch built for heavy-duty welding when water cooling is not available on site. Despite its high 350A DC rating, an oversized copper core and thick heat-dissipating body keep temperatures under control at a 60% duty cycle, making it ideal for thick plate, structural, and repair work in the field.

The robust handle and heavy cable resist abuse in shipyards, construction sites, and maintenance depots, while the generous gas passages maintain a stable shielding envelope at high current. It accepts the widely available 18-series consumable family, including large ceramic cups, heavy collets, and gas lenses, and connects through Dinse 50 fittings. Supplied with 4m or 8m cable-and-hose assemblies, the WP-27 is the dependable workhorse for high-amperage manual TIG welding.

• 350A DC Heavy Duty Rating: A large copper core and thick body sustain high current for thick-plate and structural welding.
• Air Cooled Field Ready: No water supply is required, making the torch practical for site work and remote repairs.
• 60% Duty Cycle: Efficient heat dissipation supports long welding passes without frequent cool-down stops.
• 18-Series Consumables: Accepts widely stocked collets, collet bodies, gas lenses, and large ceramic cups.
• Rugged Construction: A reinforced handle and abrasion-resistant cable withstand harsh industrial environments.
• Dinse 50 Connection: Standard connector compatible with common air-cooled TIG power sources.

The WP-27 serves heavy fabrication shops, shipyards, construction crews, and maintenance teams that weld thick carbon steel, structural members, and large castings. It performs well where water cooling is impractical and where long, high-amperage passes are routine. Pipe spool fabrication, heavy machinery repair, and tank construction are typical applications for this torch.

Supplied in a sturdy paper box with the cable-and-hose assembly and a basic consumable kit, every WP-27 is continuity-tested and function-checked before dispatch. The torch carries a 12-month warranty, and consumables such as large ceramic cups, heavy collets, and gas lenses are readily available to reduce maintenance cost and downtime.
