EX347000000350M00 - ER347 Solid MIG Welding Wire 33lb Spool

The Professional Choice for 347 and 321 Stainless

When the job calls for welding stabilized stainless steel, you can't just grab any spool off the shelf. You need a filler metal that matches the base material's chemistry and performance, and that's exactly what the Exocor ER347 MIG Wire delivers. This 33lb spool of .035" wire is the industry standard for welding 347 and 321 stainless grades, often found in high-heat applications like exhaust manifolds, refinery piping, and food processing equipment. Using the wrong wire on these materials can lead to weld failure down the road, but with ER347, you get the niobium stabilization needed to ensure the weld stands up to heat and corrosion just as well as the plate you are welding.

Beyond the chemistry, this wire is built for the welder. We know that a wire that feeds poorly makes for a long, frustrating day. Exocor has precision-wound this wire to ensure it feeds smoothly through your liner and contact tip without dragging or bird-nesting. The result is a steady, crisp arc that puts the metal exactly where you want it. It wets out flat at the toes, creating a smooth bead profile that looks professional and requires minimal grinding. Whether you are welding out of position or laying down long fillet welds in the flat position, the .035" diameter gives you the versatility to handle a wide range of material thicknesses.

Setup is standard and straightforward: run this wire on DCEP (Direct Current Electrode Positive) with your preferred stainless mix gas—typically 98% Argon with 2% Oxygen or CO2. You will appreciate the low spatter levels and the easy puddle control, which helps you avoid defects and rework. Don't take chances with critical stainless projects; equip your machine with Exocor ER347 and get the reliability and performance you need to pass inspection every time.

Why You Should Run This Wire:

• Smooth Runnability: Precision winding means less friction and fewer feed issues.
• Perfect Match: The only correct choice for 347 and 321 stainless steels.
• Great Bead Aesthetics: Lays down smooth and clean with minimal spatter.
• Reliable Arc: Consistent chemistry ensures a stable arc for high-quality X-ray quality welds.
