This 0.023 inch ER70S-6 solid MIG welding wire is sold as a two-spool pack of mild-steel wire, with a listed 10 lb weight, for thin-gauge MIG welding. This 0.023 MIG wire review is based on the Amazon listing: it suits small machines and thin steel, but only if your gun and drive rolls are set for 0.023 inch and you have shielding gas.

What this 0.023 MIG wire is for
ER70S-6 is the common mild-steel solid wire. Its extra deoxidizers help it handle light mill scale and rust better than ER70S-3, though clean steel always welds better.
At 0.023 inch it is meant for thin sheet metal, auto-body style repairs and light fabrication. For thicker plate, 0.030 or 0.035 inch is usually easier.
How to check it fits your setup
- Confirm your welder supports 0.023 inch wire in its manual or setup chart.
- Check the spool diameter and weight against your spindle, and use a spool adapter hub if needed.
- Fit a matching 0.023 inch contact tip, drive roll groove and liner.
- Plan for shielding gas, typically 75/25 argon/CO2 (C25) or 100% CO2.
- Read the listing carefully for the real pack quantity.
Pros and limitations
- Pros: A common ER70S-6 classification; the thin wire reduces burn-through on sheet; a two-spool pack means a spare is ready.
- Limitations: It needs gas (not gasless), thin wire can bird-nest if drive tension or liner is off, and listing details do not say who manufactures it or give cert documents.
Using and storing the wire
- Keep the spool in a dry place and in its bag to limit rust.
- Use light drive roll tension; thin wire bends easily.
- Start with the settings chart from your welder for 0.023 wire, then adjust.
- Ventilate the work area and wear a welding helmet, gloves and flame-resistant clothing.
- Do not weld galvanized or coated steel without proper fume control and respiratory protection.

Frequently Asked Questions
Does 0.023 inch ER70S-6 wire need shielding gas?
Yes. ER70S-6 is a solid mild-steel wire that needs shielding gas, commonly 75% argon/25% CO2 or 100% CO2. It is not a gasless flux-core wire, so running it without gas gives porous, weak welds.
What thickness is 0.023 inch wire good for?
The small 0.023 inch (0.6 mm) diameter is aimed at thin sheet metal and light fabrication, where lower amperage reduces burn-through. Check your welder’s chart for the wire size, since small machines may not support it.
Will this fit my welder?
Not automatically. Match the spool size to your spindle, and use a 0.023 inch contact tip, drive roll groove and liner. Many machines are set up for 0.030 or 0.035 inch, so change the consumables if you switch wire sizes.
Can I use it for aluminum or stainless?
No. ER70S-6 is for mild and low-alloy steel. Aluminum needs aluminum wire with argon and usually a spool gun, and stainless needs a stainless wire such as ER308L with a stainless-suitable gas.
Verdict
A reasonable mild-steel wire choice for thin sheet if your machine runs 0.023 wire and you have gas. Check the pack quantity before ordering.
