880-035-36 - Weld Mold 880 Universal TIG Rod .035" - 10lb Tube

The "Get Out of Jail Free" Rod for Mystery Metals

Every welder knows the feeling: a critical part breaks on a Friday afternoon, the machine is down, and nobody knows what kind of steel it's made of. It could be tool steel, spring steel, or some dirty cast steel from fifty years ago. This is where the Weld Mold 880 TIG Rod shines. Often referred to as the "miracle rod" in maintenance shops, the 880 is your best defense against cracking and weld failure when dealing with mystery metals or dissimilar combinations.

This 10lb tube of .035" TIG rod gives you the precision you need for fine crack repairs, building up worn shafts, or extracting broken bolts. The 880 alloy runs with a smooth, stable arc that wets out beautifully, allowing you to tie into the sidewalls without fighting the puddle. Because it is incredibly strong (120,000 PSI) yet ductile, it stretches instead of snapping as the weld cools. This means you can weld a stainless bracket to a mild steel frame, or repair a high-carbon tool steel die, without worrying about the weld popping loose as soon as it cools down.

Why keep Weld Mold 880 in your rod oven? Because it saves time and reputation. Instead of guessing with a 309 or 70S-6 and hoping for the best, you can use the 880 with confidence. It's also excellent for "buttering" faces—laying down a layer of 880 on a difficult steel before welding it to something else. Whether you are fixing heavy earthmoving equipment, repairing automotive components, or doing general plant maintenance, this rod pays for itself the first time it saves a part that everyone else said couldn't be fixed.

Common Applications

• Broken Bolt Extraction: Build up a nub on a broken bolt inside a hole to grab it with vice grips.
• Dissimilar Joining: Welding stainless to mild steel, or spring steel to carbon steel.
• Crack Repair: Fixing cracks in transmission housings, gears, and heavy machinery frames.
• Tool & Die: Repairing chipped edges on tool steel dies.
