Harris Products Group's 4401374 Ironworker kit is an extra-heavy-duty combination outfit built around the V-Series design, and it runs on all fuel gases including acetylene. The kit ships with a Victor-compatible V1-101-1 cutting tip and a 23A90-5 welding/brazing tip, with optional tips available to extend capacity up to 8 inches for cutting and 1/2 inch for welding. The torch handle features tube-within-a-tube construction with O-ring seals and replaceable FlashGuard check valves, while the mixing system is designed to resist flashback damage. Regulators are fitted with encapsulated seats, internal filters, and PTFE seats to guard against particulate contamination, and the included Model 450 regulator provides dual-scale 2.5-inch brass gauges and a tamper-proof safety relief valve. A 20-foot, 1/4-inch twin hose, Shade 5 safety glasses, a handheld ignitor, and an insulated tool bag round out the package.
