Buying Guide

Choose wire chemistry for your process

Select ER70S‑6 solid wire for MIG with shielding gas or E71T‑GS flux‑core for gasless welding and field work

Match wire diameter to joint fit‑up

Use .023–.035 in wire sizes: thinner (.023) for thin sheets and tight lap seams, thicker (.030/.035) for heavier panels and higher deposition

Consider spool weight and frequency

Buy 2–10 lb spools or multi‑packs based on how often you weld to reduce downtime and storage of partial spools

Look for consistent chemistry and cleanliness

ER70S‑6 offers deoxidizers that improve arc stability and reduce spatter, important for neat lap welds on auto sheet metal

Match flux‑core when shielding gas is impractical

E71T‑GS flux‑core wires perform well outdoors or in poorly ventilated shops where gas shielding is difficult
