Factory Direct SFT-61 Welding Torch, >15mm Max Thickness, 2 Flames, Balanced Pressure Type for HVAC & Industrial Repairs

Actually handles thickness beyond 15mm with dual flames, which is what you need for heavy HVAC line repairs and industrial fabrication where single-torch setups just stall out. The balanced pressure design means you're not fighting with gas flow when switching between LPG and propane—it self-regulates pretty much, so the flame stays consistent through a long run.

We've had these in continuous production use for about six months now, and the brass valve with stainless steel pipe holds up better than the all-brass units that used to warp on us. Most buyers go with the SFT-61 for air conditioning condenser repairs or boiler work where teh joint needs to take sustained heat without torch body getting too hot to handle.

2 flames isn't just for show—it lets you preheat wider areas before laying down the weld, which cuts down on distortion in sheet metal. The 360-degree swivel tip (we include it standdard) makes a real difference when you're working inside a cramped duct run or behind a compressor.

ISO9001 cert is there, and each unit ships with a COA for the valve assembly, but if you need third-party HPLC verification on the gas flow components, that's a separate request with about 2 weeks lead time. 5. MOQ is 50 units or so for direct factory pricing, though our company can do smaller test orders (usually 10-15 pieces) if you're qualifying a new suplier.
