FAQ
Q1: What type of gas should I use with this welding wire?
This wire is designed for use with CO₂ or Argon/CO₂ mixed shielding gas.
Q2: What is ER70S-6 best used for?
It is ideal for mild steel welding, especially when working with slightly rusty or dirty materials.
Q3: Does this wire produce a lot of spatter?
No, the copper coating and optimized composition help reduce spatter and provide a smooth arc.
Q4: Which diameter should I choose?
0.023" for thin materials
0.030" for general-purpose welding
0.035" for thicker materials
Q5: Is the wire protected from moisture?
Yes, the spool is wrapped in moisture-resistant plastic film to maintain quality during storage.
