TIG Rod ER70S-6 Mild Steel Copper-Coated – 2.4mm Diameter, 1M Length

Overview

This ER70S-6 copper-coated steel rod is engineered for high-deoxidizer content, delivering superior wetting and flatter bead profiles—ideal for fast single-pass welding on mild and low-alloy steels. The formulation tolerates rusty and dirty surfaces without pre-cleaning, making it a practical choice for field repairs and fabrication shops working with tight schedules.

If your customer base includes stainless steel applications, consider stocking stainless-grade ER316L rods as a natural complement to this mild-steel offering.

Key Features

• High Deoxidizer Content: Enhanced Si and Mn levels (1.40–1.85% Mn, 0.80–1.15% Si) for improved wetting and cleaner bead geometry
• Copper-Coated Surface: Improved electrical conductivity and reduced oxidation during storage
• Single-Pass Performance: Engineered for direct application on unclean surfaces, reducing preparation time and labor
• Multi-Gas Compatibility: Compatible with 75% Argon + 25% CO₂, 98% Argon + 2% CO₂, or 100% CO₂ shielding gas
• AWS/DIN/EN/JIS Certified: Meets international welding standards (AWS A5.18, DIN 8559, EN 440, JIS Z3312)

Applications

• Mild and Low-Alloy Steel Repairs: Structural components, frames, and fabrications
• Small-Diameter Tubes and Pipes: Consistent penetration on thin-wall assemblies
• Sheet Metal Work: Flat, aesthetically acceptable beads with minimal distortion
• Field Welding: Tolerates less-than-ideal surface conditions without sacrificing joint quality

Business Advantages for Resellers

• High Turnover Potential: ER70S-6 is the industry workhorse for general-purpose steel welding—consistent demand across automotive, construction, and fabrication shops
• Bulk Purchase Economics: 5 kg bundles offer efficient inventory management; available in smaller spools (0.7 kg) for customer upsell or trial orders
• Margin-Friendly: Competitive production cost with premium performance specifications justifies healthy retail markups
• Storage Stability: Copper coating extends shelf life and reduces customer complaints about degraded wire
• Cross-Sell Ready: Position alongside stainless-steel rods (ER308LSi alternatives) to capture broader welding applications

Why Stock This Wire?

ER70S-6 represents the intersection of performance and pragmatism. Higher deoxidizer content means less cleanup, faster travel speeds, and fewer callbacks for poor welds—directly translating to customer satisfaction and repeat orders. The copper coating ensures consistent arc starts and minimal wire degradation in typical shop storage.

For shops handling mixed materials, this rod pairs efficiently with stainless alternatives, allowing you to serve a broader customer base without overextending inventory complexity.
