MIG welding wire is a continuously fed consumable electrode used in gas metal arc welding (GMAW). A welding gun feeds the wire into the arc, where it melts and supplies filler metal to the weld joint. The molten weld pool is protected by an appropriate shielding gas.
KYA lists mild steel MIG welding wire products, including ER70S-6 in copper-coated configurations. These products are used in compatible welding applications involving carbon steel and suitable low-alloy steels.
Select MIG welding wire according to the specified filler classification, wire diameter, welding current, shielding gas and required weld-metal performance.
ER70S-6 is a commonly specified carbon steel solid welding wire used in GMAW applications. Its manganese and silicon deoxidizer content supports welding performance on suitably prepared carbon steel materials, including some steels with limited mill scale or surface oxidation.
KYA lists ER70S-6 products for CO2 and suitable argon-based mixed shielding gases. The correct gas composition, welding parameters and weld procedure depend on the base metal and application.
ER70S-6 wire is used in general steel fabrication, machinery manufacture, structural components and other approved carbon steel welding applications.
ER70S-G is a filler metal classification with composition requirements that should be verified through the applicable product specification. It should not automatically be treated as identical to ER70S-6.
For ER70S-G inquiries, provide the required chemical composition, applicable classification, base metal, shielding gas and mechanical properties. Product availability and suitability should be confirmed for the required welding procedure.
TIG welding, also known as gas tungsten arc welding (GTAW), uses a non-consumable tungsten electrode to generate the arc. A separate filler rod or wire may be added to the weld pool as required by the joint and welding procedure.
KYA lists copper-coated TIG welding wire products. Buyers should verify the filler metal classification, diameter, length or supply form, base metal compatibility and specified shielding gas.
MIG welding operating parameters should not be applied directly to TIG welding. The processes use different electrode arrangements and equipment settings.
Submerged arc welding (SAW) uses a continuously fed consumable wire electrode and a granular flux that covers the welding arc. The flux and wire must be selected as a compatible system to achieve the required weld properties.
KYA's published welding material range references H08A (EL12), H08MnA (EM12) and H10Mn2 (EH14) submerged arc welding wire grades. The exact grade, flux pairing and applicable classification should be confirmed for the selected product.
SAW wire is used in suitable mechanized welding operations for steel structures, heavy fabrication and other industrial assemblies where the welding procedure permits the process.
KYA also lists welding wire for collated coil nail production. This product has a different industrial purpose from consumable arc welding filler wire used for metal joining.
Manufacturers should provide the coil nail production equipment, wire dimensions, material and joining requirements when requesting this type of industrial welding wire.
Different welding processes require different consumable forms and operating conditions. Select the welding wire according to the process and the applicable welding procedure.
| Welding Process | Filler Arrangement | Protection Method | Typical Application |
|---|---|---|---|
| MIG / GMAW | Continuously fed consumable wire electrode | External shielding gas | General steel fabrication and manufacturing |
| TIG / GTAW | Separate filler rod or wire with tungsten electrode | Inert shielding gas | Precision joints and controlled welding operations |
| SAW | Continuously fed consumable wire electrode | Granular welding flux | Mechanized and heavy steel fabrication |
The required welding wire classification, shielding medium and operating range must be verified for the selected process. Filler metals should not be interchanged solely because they have a similar diameter or steel composition.
ER70S-6 is widely used as a mild steel solid wire for gas metal arc welding. The nominal filler composition includes manganese and silicon deoxidizers. Welding characteristics depend on the wire quality, shielding gas, base metal, equipment settings and welding procedure.
The following chemical composition and mechanical property figures are reference values published in KYA's welding wire information. They should not be interpreted as guaranteed results for every production batch or shielding gas combination.
The table below shows the published elemental analysis. Values are expressed as percentages by mass.
| C | Mn | Si | P | S | Ni | Cr | Cu | V |
|---|---|---|---|---|---|---|---|---|
| 0.08 | 1.51 | 0.89 | 0.015 | 0.013 | 0.016 | 0.021 | 0.18 | 0.003 |
C is carbon, Mn manganese, Si silicon, P phosphorus, S sulfur, Ni nickel, Cr chromium, Cu copper and V vanadium. The required chemical limits must be checked against the applicable filler metal classification and the supplied product specification.
The following values are KYA's published reference mechanical properties. Actual deposited weld metal performance can vary with shielding gas, welding parameters, testing conditions and the selected product.
| Mechanical Property | Published Reference Value |

| Reference Current | 100 A | 150 A | 280 A | 350 A |
These are reference ranges rather than a complete welding procedure. Appropriate values depend on wire feed speed, transfer mode, welding position, shielding gas, base material, electrode stickout and equipment. Qualified welding procedures must take precedence where required.
KYA's original product information references CO2, Ar + 5% CO2 and Ar + 2% O2 shielding gas configurations. Additional suitable argon-CO2 mixtures may be specified for particular ER70S-6 welding products and procedures.
The selected shielding gas influences arc behavior, metal transfer, penetration, spatter and deposited weld metal properties. Confirm the gas composition according to the wire product and the required welding procedure.
| Shielding Gas | Selection Considerations |
|---|---|
| 100% CO2 | Common for compatible carbon steel GMAW applications; evaluate penetration and spatter behavior |
| Argon + CO2 Mixture | Select the ratio for the intended metal transfer, arc characteristics and welding procedure |
| Argon + 2% O2 | Use only where specified for the wire, base metal and qualified process |
