YESWELDER Mild Steel ER70S-6 TIG Rod
ER70S-6 is a copper-coated mild steel TIG filler rod designed for reliable welds on common steels. Its composition includes manganese and silicon deoxidizers that support higher welding currents when using 100% CO2 shielding gas, while helping produce a smoother bead with minimal post-weld cleanup. The rod also performs well with argon-containing shielding gas, which can further improve bead appearance and reduce spatter. This makes it a solid choice for fabricating frames, brackets, and other mild steel components where weld cleanliness matters.
- Copper-coated mild steel composition for strong welds
- Deoxidizers support higher current and smooth bead with CO2 or argon-based shielding
- Optimized for mild and low-alloy steel welds
- Stable arc with TIG welding setups
For best results, ensure proper gas shielding and clean base metal surfaces. Store rods in a dry environment to prevent moisture uptake, which can affect weld quality and spatter control during longer sessions.
YESWELDER E7018 3/32″ 5LB Rod
E7018 is a low-hydrogen iron powder electrode that delivers high-quality welds suitable for X-ray inspections. It performs well in all positions on AC or DC reverse polarity welding current. This electrode is particularly useful for welding medium-grade carbon steels when preheat is not used and on cold-rolled steels that tend toward porosity with conventional electrodes. The arc remains steady with low spatter, and it offers easy re-striking and high deposition efficiency, making it a versatile option for structural work and repairs where consistent, crack-resistant joints are essential.
- All-position welding with AC or DC reverse polarity
- Low hydrogen iron powder formulation for strong, clean welds
- Suitable for non-preheated carbon steels and cold-rolled steels
- Steady arc with low spatter and good deposition
Keep stored in a dry environment to maintain low hydrogen content. Use proper ventilation when welding to manage fumes, especially on projects involving thicker carbon steels or joints with tight fits in confined spaces.
ARCCAPTAIN E7018 3/32″ 5LB Rod
ARCCAPTAIN’s E7018 welding rod is a low-hydrogen iron powder electrode designed for high-strength carbon steel welds. It supports welding in any position with AC or DC reverse polarity and is especially noted for excellent X-ray values, high tensile strength, and good resistance to cracking. The 3/32″ diameter paired with a 14″ length (typical for this model) makes it well-suited for mid-size fabrication, repairs, and shop work where crack resistance and consistent deposition are important factors for long-term joint integrity.
- Low hydrogen iron powder electrode
- All-position welding with AC/DC reverse polarity
- Outstanding tensile strength and crack resistance
- Good for high-deposition efficiency and x-ray quality welds
When working on critical joints, confirm proper pre-weld alignment and avoid excessive heat input that could affect base metal properties. Proper storage helps prevent hydrogen uptake that can influence cracking susceptibility.
Saker E6013 Welding Rod
E6013 is a versatile carbon steel welding rod known for easy arc action, suitability for AC and DC welding, and reliable performance in light to medium fabrication tasks. The flux coating promotes slag formation that aids slag removal, making vertical-down welds largely self-cleaning. It offers good all-position capability and shallow penetration, which is advantageous when welding poorly fitting joints or thin sections. This makes E6013 a practical choice for beginners or for repairs where speed and clean-up ease matter most.
- Versatile carbon steel electrode for AC/DC
- All-position welding with easy arc start
- Flux aids slag removal and clean welds
- Shallow penetration suitable for light gauge steel
Store in a dry place to maintain coating integrity and minimize moisture-related porosity. For welds in thicker sections, pairing E6013 with proper joint fit-up and controlled heat input improves the overall weld quality.
TOOLIOM Mild Steel ER70S-6 3/32″ TIG Rod
TOOLIOM’s ER70S-6 TIG filler rod is designed for reliable welding on mild steel. The copper-coated composition supports stable arc and smooth bead formation, especially when using shielding gases such as 100% CO2 or argon/CO2 mixes. The 3/32″ diameter and 16″ length suit a range of TIG welding tasks from fabrication to repair work, with strong deoxidizers helping to reduce porosity and improve weld cleanliness at moderate currents. It is a practical option for DIYers and small shops.
- Copper-coated mild steel TIG rod
- Gas compatibility with CO2 or argon/CO2 blends
- Stable arc, less spatter, and smooth beads
- Diameter 3/32″, length 16″, 5 lb pack
Keep rods dry and store in a climate-controlled area to maintain performance. For best results, pair with appropriate TIG settings and base-metal prep to minimize cleaning needs after welding.
Buying Guide
Key Factors to Consider
Choosing the right welding rod depends on material type, welding process, and the desired joint quality. For steel, consider whether the project requires strong, crack-resistant joints (low-hydrogen E7018) or easier, all-position performance (E6013). Shielding gas compatibility matters for TIG work with ER70S-6 rods, as gas composition can influence bead appearance and spatter. Size and packaging affect handling and heat input control, while moisture exposure can compromise hydrogen-sensitive rods.
Rod Types and When to Use Them
E7018 rods are favored for structural steel and critical joints due to low hydrogen content and high ductility. They excel in all-position welding but may require preheat and interpass control on thicker members. E6013 rods are versatile, easy to use, and forgiving for beginners, suitable for light fabrication and repairs where quick cleanup is needed. ER70S-6 variants provide strong welds on mild steel with TIG or MIG processes and are compatible with various shielding gas blends, often yielding cleaner beads with proper technique.
Process and Position Considerations
Assess your welding process ( TIG vs Stick) and position needs. TIG welding with ER70S-6 is common for clean, precise welds on thin to medium sections, but it demands steady hand control and shielding-gas management. Stick electrodes like E7018 or E6013 are more forgiving in field conditions and on thicker metals, offering robust performance in all positions. For beginners, starting with E6013 can build foundational skills, while gradually integrating E7018 for more demanding joints.
Storage, Handling, and Quality Assurance
Store electrodes in a dry environment to prevent hydrogen uptake, which can lead to cracking in some steels. Keep filler rods sealed until use, especially for hydrogen-sensitive types. Inspect rods for moisture stains or corrosion before use, and ensure your welding setup provides stable current, correct polarity, and adequate shielding gas. If you’re working on critical components, verify that your material and filler composition meet project specifications and applicable welding codes.
