KYA ER70S-6 MIG Welding Wire 1.0mm 33lb is a solid carbon steel welding wire for gas metal arc welding (GMAW/MIG). The featured product combines a 1.0mm wire diameter with a 15kg / 33lb spool, making it suitable for industrial fabrication, structural steel, machinery, shipbuilding, bridges, pressure vessels and general carbon steel welding.
ER70S-6 contains relatively high levels of manganese and silicon deoxidizers, helping provide stable arc characteristics, good weld-puddle fluidity and reliable bead formation when welding carbon and low-carbon steels. The wire can be used with 100% CO2 or suitable argon/CO2 shielding-gas mixtures, depending on the required penetration, spatter level, transfer mode and weld appearance.

ER70S-6 is a widely used AWS classification for solid carbon-steel welding wire used in gas-shielded arc welding. In general terminology, ER identifies an electrode or rod, 70 corresponds to the nominal 70 ksi tensile-strength class, S identifies solid wire, and 6 identifies the specific chemistry classification.
ER70S-6 is commonly selected because its manganese and silicon deoxidizer content supports welding of general carbon steels and provides good tolerance of normal fabrication conditions compared with lower-deoxidizer solid-wire classifications.
The following values are the chemical-composition data listed for KYA ER70S-6 welding wire. Manganese and silicon are important deoxidizing elements that contribute to the welding characteristics of the ER70S-6 classification.
| 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 |
| Tensile Strength | Yield Strength | Elongation | Impact Value | Test Temperature | Shielding Gas |
|---|---|---|---|---|---|
| 545 MPa | 452 MPa | 29% | 91 J | -30°C | CO2 |
Mechanical properties depend on welding procedure, shielding gas, heat input and test conditions. Buyers requiring certified values for a specific project should request the applicable product certificate or test report.
| Wire Diameter | Welding Current | Welding Voltage | Reference Current |
|---|---|---|---|
| 0.8mm | 50–120A | 15–22V | 100A |
| 1.0mm | 70–180A | 18–24V | 150A |
| 1.2mm | 80–350A | 18–34V | 280A |
| 1.6mm | 140–500A | 20–42V | 350A |
For the featured 1.0mm ER70S-6 wire, the KYA reference range is 70–180A and 18–24V. Actual welding-machine settings should always be established from the welding procedure, machine manufacturer recommendations and trial welding.
ER70S-6 can be welded with 100% CO2. CO2 is widely used for carbon-steel fabrication and generally provides strong penetration. Depending on the welding parameters, it can produce more spatter and a less smooth bead appearance than argon-rich mixed shielding gas.
Argon/CO2 blends are commonly selected when reduced spatter, smoother arc characteristics and improved bead appearance are important. The optimum mixture depends on transfer mode, base-metal thickness and the approved welding procedure.
KYA's ER70S-6 product range lists CO2, Ar + 5% CO2 and Ar + 2% O2 among applicable shielding-gas options. Confirm the required gas and procedure before production use.
The 1.0mm diameter provides a practical balance between deposition rate and controllability for a wide range of carbon-steel fabrication. It is commonly selected for medium-duty MIG welding where smaller wire may limit productivity and larger wire is unnecessary.
Suitable for fabricated steel frames, structural components, brackets, frames and general workshop welding of compatible carbon steels.
ER70S-6 is used in machinery fabrication, construction equipment, agricultural equipment and related welded carbon-steel assemblies.
Gas-shielded ER70S-6 wire is used for suitable carbon-steel fabrication in shipbuilding and related welded structures subject to the applicable welding procedure and project approval requirements.
ER70S-6 can be used for bridge components and structural fabrication when the filler-metal classification and welding procedure satisfy the applicable project specification.
Applications can include pressure-vessel components, tanks and industrial equipment when approved filler-metal specifications, welding procedures and quality-control requirements are followed.
This page focuses on the 1.0mm diameter, 15kg / 33lb spool. KYA's broader ER70S-6 range also includes other wire diameters and spool weights for different welding equipment and production requirements.
| Classification | Diameter | Available Package |
|---|---|---|
| ER70S-6 / ER50-6 | 0.8mm | 5kg / 15kg / 20kg |
| ER70S-6 / ER50-6 | 0.9mm | 5kg / 15kg / 20kg |
| ER70S-6 / ER50-6 | 1.0mm | 5kg / 15kg (33lb) / 20kg |
| ER70S-6 / ER50-6 | 1.2mm | 5kg / 15kg / 20kg |
| ER70S-6 / ER50-6 | 1.6mm | 5kg / 15kg / 20kg |
Industrial buyers should specify more than the ER70S-6 grade alone. Wire diameter, spool size, shielding gas, base-metal grade, welding process and certification requirements all affect product selection.

ER70S-6 is a solid carbon-steel MIG/GMAW wire used for steel structures, machinery, shipbuilding, bridges, pressure vessels, construction equipment and general carbon-steel fabrication.
ER70S-6 is an AWS solid-wire classification. ER identifies electrode or rod, 70 identifies the nominal 70 ksi tensile-strength class, S means solid wire, and 6 identifies the chemical-composition classification.
1.0mm is approximately 0.039 inch, so it is commonly treated as the metric size corresponding closely to .040 inch. Confirm that your drive rolls, contact tip and wire feeder are designed for the selected wire diameter.
KYA lists a reference range of 70–180A and 18–24V for 1.0mm wire, with 150A as a reference current. Final settings depend on wire-feed speed, shielding gas, material thickness, joint design and welding position.
ER70S-6 can be used with 100% CO2 and suitable argon-based mixed gases. KYA lists CO2, Ar + 5% CO2 and Ar + 2% O2 within its ER70S-6 range. Shielding-gas selection should follow the approved welding procedure.
Solid ER70S-6 MIG wire is normally used with DCEP, or direct-current electrode positive. Always confirm the welding-machine and procedure requirements before welding.
Yes. ER70S-6 is commonly used with 100% CO2 for carbon-steel welding. CO2 generally provides strong penetration, while argon-rich mixed gas can provide lower spatter and smoother bead appearance depending on the process.
ER70S-6 has relatively strong deoxidizing capability because of its manganese and silicon content, which makes it useful in normal fabrication conditions. However, oil, heavy rust, moisture, paint and excessive mill scale should still be removed whenever required by the welding procedure and quality standard.
ER70S-6 generally contains higher manganese and silicon deoxidizer levels than ER70S-3. It is therefore widely selected for general fabrication where additional deoxidizing capability and good weld-puddle wetting are desirable.
The featured product is supplied on a 15kg / approximately 33lb spool, a common package size for industrial MIG/GMAW welding.
KYA's ER70S-6 range includes 0.8mm, 0.9mm, 1.0mm, 1.2mm and 1.6mm diameter options. The correct diameter depends on plate thickness, deposition requirement, welding current and equipment capacity.
KYA lists ER70S-6 for flat, horizontal, vertical and overhead welding. Actual positional capability depends on transfer mode, wire diameter, welding parameters, joint geometry and the qualified welding procedure.
Specify the AWS classification, wire diameter, spool weight, base-metal application, shielding gas, required certifications, quantity, packaging and destination market.
