0311-0307 - Victor 4-MFN Propane Heating Nozzle

Turn Up the Heat with the Victor 4-MFN

When you need to bend a heavy I-beam, preheat a thick casting, or straighten a warped steel plate, a standard welding tip just won't cut it. You need the Victor 0311-0307 4-MFN Heating Tip. This is a heavy-duty "rosebud" style nozzle designed to dump massive amounts of heat into your workpiece quickly and efficiently. Built by Victor, the most trusted name in gas equipment, this tip is a workhorse for any welder or fabricator dealing with heavy steel.

The "MFN" designation means this tip is optimized for Propane and Natural Gas. Why does that matter? Propane is not only cheaper than acetylene, but it also allows you to use much larger tips like this Size 4 without worrying about the withdrawal rate limits of acetylene cylinders. You can run this tip hard and long to get deep, soaking heat into the thickest materials. The multi-flame face creates a broad heat zone, preventing hot spots and ensuring the entire area reaches the target temperature evenly. It’s perfect for preheating prior to welding to prevent cracking, or for getting metal red-hot for easy bending.

Compatibility is key in any shop. The 4-MFN fits standard Victor 300 Series torch handles, which are the heavy-duty handles found in most industrial rigs. If you have a big Victor torch, this tip will likely screw right on. The construction is rugged, featuring a heavy copper shell that resists damage from drops and withstands the intense reflected heat of the job. Don't waste time trying to heat a 1-inch plate with a cutting torch or a small welding tip.

Using the 4-MFN is straightforward. Hook it up to your heavy-duty handle, set your regulators for propane (remember, propane needs different pressure settings than acetylene), and light it up. You'll get a roaring, high-BTU flame that makes short work of cold steel. Whether you are in a farm shop, a structural steel yard, or an oilfield maintenance truck, having a proper heating tip like the Victor 4-MFN in your kit turns impossible bending jobs into easy work.
