OVERVIEW

Exocor ER70S-6 .030" Copper-Free MIG Wire – 44lb Spool

Maximize your productivity and weld quality with the Exocor ER70S-6 Copper-Free MIG Wire. This 0.030-inch solid wire comes on a 44lb (20kg) spool, designed to fit standard industrial wire feeders. It is the ideal solution for welders who demand reliability and are tired of dealing with the maintenance headaches caused by copper-flaking in traditional wires. This wire is formulated to provide the smooth feedability you expect from a premium consumable, ensuring a consistent arc even during long welds or complex robotic operations.

The ER70S-6 classification identifies this as a general-purpose mild steel wire with high deoxidizing properties. If you are welding on structural steel, farm implements, or automotive parts that aren't perfectly sandblasted, the added silicon and manganese in this wire help float impurities to the surface, preventing porosity and ensuring a sound weld. The 0.030" diameter is incredibly versatile, offering enough deposition for medium-thickness plate while remaining controllable enough for thin gauge sheet metal work, reducing the risk of burn-through.

What sets this specific Exocor wire apart is the Copper-Free finish. While it looks different on the spool than the shiny copper wires you might be used to, it performs better. The advanced surface lubricant ensures the wire glides through the liner with minimal drag. Because there is no copper coating to chip off at the drive rolls, your liner stays clear of conductive dust, and your contact tips suffer less erosion. This results in a stable arc, less spatter to scrape off later, and a better-looking final product. It is compatible with both 100% CO2 and Argon/CO2 shielding gas mixes, giving you flexibility based on your shop's setup.

FAQ

Copper-free wire eliminates the issue of copper flaking, which can clog wire liners and contact tips. This results in smoother feeding, a more stable arc, less equipment maintenance, and reduced welding fumes.

This wire can be used with 100% CO2 for deeper penetration and lower cost, or an Argon/CO2 mix (typically 75/25) for a smoother arc, less spatter, and better bead appearance.

Yes, the ER70S-6 classification indicates high levels of manganese and silicon deoxidizers, making it very capable of welding over moderate rust, mill scale, and oil without causing porosity.

This is a 44lb (20kg) spool. It typically requires an industrial wire feeder capable of holding large diameter spools (usually 12-inch diameter spools).

Yes, as a solid MIG wire, it can be used in all positions (flat, horizontal, vertical, and overhead), especially when using Short Circuit transfer mode with the .030" diameter.

No, Exocor uses a proprietary surface treatment that protects the wire from oxidation during storage, similar to how copper coating protects traditional wire.

This wire requires DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.
