TTU949 - RG45 Mild Steel Oxy-Acetylene Welding Rod 1/8" (1lb Tube)

Reliable RG45 Rods for Classic Oxy-Acetylene Welding

When you are firing up the torches for some old-school oxy-acetylene welding, the quality of your filler rod defines the ease of your job. Our RG45 Gas Welding Rods in 3.2mm (1/8") are the trusted choice for welders who appreciate the art of gas welding. Designed for working on mild steel and wrought iron, these rods provide the smooth flow and wetting action you need to lay down a perfect stack of dimes. Whether you are fixing an exhaust system, restoring a vintage automobile body, or repairing steel piping in the field, these rods give you ultimate control over the puddle.

We know that rusty rods are a nightmare to weld with, which is why these RG45 rods come with a high-quality copper coating. This coating keeps them bright and clean in your toolbox or truck, preventing rust even in humid environments. It also helps the rod slide smoothly through your gloved fingers as you feed the puddle, preventing the stuttering that can mess up a bead. The 1/8-inch diameter is a true workhorse size—thick enough to fill significant gaps and build up worn metal on plate, yet manageable enough for detailed work on pipe or tubing. For most clean steel jobs, you can leave the flux on the shelf; just set a neutral flame, establish your puddle, and let the rod do the work.

This 1lb tube is perfect for the welder who needs to keep a stash of gas rods handy but doesn't want to buy a 50lb box. The 36-inch length gives you plenty of reach, keeping your hands cool and allowing for long runs before you need to grab a fresh rod. If you are looking for a rod that behaves predictably and produces soft, ductile welds that are easy to file or grind, this is it. Don't settle for using coat hangers or inferior wire; use the proper tool for the job.

Practical Application Tips

For the best results, ensure your base metal is free of heavy scale, oil, and rust before you start. A neutral flame is key—too much oxygen will burn the steel, and too much acetylene will add carbon and make the weld brittle. These rods are forgiving and allow you to manipulate the molten pool to bridge gaps or wash in the toes of the weld. While they are designed for steel, remember they aren't for cast iron repairs—stick to steel and wrought iron for the best results.
