Premium Quality: Solid carbon steel ER70S-6 wire for single or multi-pass Gas Metal Arc Welding (GMAW); the most common mild steel MIG wire.
Optimal Performance: Features high manganese and silicon deoxidizers for smooth arc stability, minimal splatter, and reduced post-weld cleanup.
Versatile Use: Ideal for general shop, construction, farm implement fabrication, structural works, and automotive body repairs on sheet metal or rusty plates.
High Compatibility: Designed for use with 100% CO2 or 80% Argon / 20% CO2 mixed shielding gases to suit various applications.
Durable Spool: Supplied on a robust, anti-fragile ABS plastic spool, engineered for reliable, consistent feeding and machine operation during transport and use.
Q: Do I need to change my polarity for this wire?
Q: Do I need to change my polarity for this wire?
A: Yes! This is the opposite of flux-core. You must use DCEP (Electrode Positive). Your torch should be in the (+) terminal and your ground clamp in the (-) terminal. If you use the flux-core setting, the arc will be violent and the weld will be black.
Q: Which gas should I use with this .030" wire?
Q: Which gas should I use with this .030" wire?
A: For the best-looking, lowest-spatter welds on thin steel (automotive), use C25 (75% Argon / 25% CO2). If you need deeper penetration on thick farm equipment and want to save money on gas, 100% CO2 works well but produces more spatter.
Q: Can I weld 1/4" steel with this .030" wire?
Q: Can I weld 1/4" steel with this .030" wire?
A: Yes, but you will need to turn your voltage up high and use a slower travel speed. For consistent 1/4" and thicker work, most pros switch to .035" wire, but .030" is a great "all-around" size for a 140A to 210A welder.
Q: Why does the wire keep sticking inside the copper contact tip?
Q: Why does the wire keep sticking inside the copper contact tip?
A: This is called "Burn-back." It usually happens because your Wire Feed Speed is too low or your voltage is too high. It can also happen if the tip is the wrong size; ensure you are using a .030" tip.
Q: My weld has tiny holes (porosity) everywhere. Is the wire bad?
Q: My weld has tiny holes (porosity) everywhere. Is the wire bad?
A: It is rarely the wire. Check your gas! Make sure the cylinder is open, the regulator is set to 20–25 CFH, and there is no fan blowing the gas away. Also, ensure the metal is ground to a shiny finish.
Q: How long will a 10 lb spool last?
Q: How long will a 10 lb spool last?
A: For a hobbyist, a 10 lb spool is a significant amount—roughly 10 to 15 hours of actual "trigger time." It is much more economical than buying five small 2 lb spools.
