Uniweld wh350 Welding Handle 7.5 in Victor Style

Product Description

The UNIWELD wh350 is a medium-duty oxy-fuel torch handle designed for welding, cutting, and heating applications across acetylene, natural gas, propane, and propylene fuel systems. Built with a brass body and stainless steel ballpoint valves with Teflon packing, the wh350 measures 7.5 inches in overall length with a 0.75-inch handle diameter. It uses a 9/16-inch-18 UNF left-hand inlet connection with a B-size hose fitting and includes four O-ring seals. The tube-within-a-tube design and built-in B flashback arrestors are key safety and performance features. Installed by certified welders and pipefitters, this handle is a direct-fit Victor-style torch body suited for shop and field use.

The wh350 supports welding stock up to 1.25 inches thick and accommodates a two-hose setup for oxygen and acetylene or other compatible fuel gases. It is used in fabrication shops, HVAC service, plumbing, and industrial maintenance where a reliable mid-duty torch handle is required. Compatible heating tip series MFA-1, welding and brazing tip series W-1, compatible tip series 3-101-1, and cutting attachments CA350 and CA350B all fit this handle, making it a versatile platform for multiple torch operations without swapping handles.

Installation Notes

Installation should be performed by a qualified welder or pipefitter familiar with oxy-fuel equipment. Shut off all gas supplies and depressurize hoses before assembling or disassembling the handle. Use appropriate leak-detection solution on all connections after assembly — never use an open flame to check for leaks. Follow applicable OSHA and CGA guidelines for oxy-fuel torch handling and storage.
