T169-2.5 - C-32 Cast Iron TIG Welding Rod 3/32" (2.5mm) - 10lb Tube

Professional Grade C-32 TIG Rod for Cast Iron Welding

When you need to fix cast iron and failure isn't an option, reach for the C-32 Cast Iron TIG Rod. This 3/32" (2.5mm) filler metal is the go-to solution for welders who demand precision and machinability. Cast iron is notorious for being difficult to weld, but the C-32 rod simplifies the process by providing a stable, smooth arc and a deposit that flows wet and fuses tightly with the base metal. Designed for the TIG (GTAW) process, this rod gives you the ultimate control over heat input, which is critical for preventing cracks in brittle iron castings.

The C-32 formula is specifically balanced to create a soft, ductile weld bead that can be machined easily. This means you can weld up a worn surface or a crack and then machine it down to a seamless finish without destroying your cutting tools. It is highly effective on gray iron, ductile iron, and malleable iron. The 10 lb tube ensures you have plenty of material for large projects or ongoing maintenance needs, and the 36-inch length is standard for comfortable manual feeding.

Using 100% Argon shielding gas, this rod produces a clean weld with minimal spatter and no slag to chip away, unlike stick electrodes. This cleanliness is vital when repairing parts that require a perfect seal, such as hydraulic components or liquid-handling equipment. For best results, preheating the cast iron part is recommended to further reduce thermal shock, but the superior ductility of the C-32 alloy provides a significant safety margin against cracking even in challenging conditions.

Features & Benefits

• Machinable Deposit: Welds can be drilled, tapped, and milled easily.
• Crack Resistant: High ductility absorbs cooling stresses.
• Precise Control: TIG process allows for delicate repairs on thin or complex sections.
• Versatile: Works on multiple grades of cast iron and for joining iron to steel.
