  • A 0.023 in diameter — the 0.6 mm (0.02 in) class — which is what this hub’s buying tip says the thin end of the range needs
  • The only wire of this size anywhere in this hub, in either half
  • The highest price per spool on this shelf, for the least metal per meter

Best for: Car-body panel and thin sheet, where a 0.8 mm (0.03 in) wire blows holes

This hub’s buying tip is unusually direct: match the wire diameter to the thinnest metal you weld, because 0.6 mm (0.02 in) gives control on car-body sheet and 1.0 mm (0.04 in) struggles below 2 mm (0.08 in) — and the thin end is where mistakes cost a panel. Until this shelf gained its American half, there was no 0.6 mm (0.02 in)-class wire in the hub at all. This is it: 0.023 in, which is the American designation for the same size.

What it buys is heat control. A finer wire carries less current at a given feed speed, so less energy goes into a panel that is only eight tenths of a millimeter thick. That is the whole difference between a tack that holds and a hole you then have to fill. Ten pounds of 0.023 in wire is also a great many meters, so the spool outlasts its price.

Two things to plan for. A fine wire wants a contact tip bored for it and a liner that will not let it buckle, and neither is mentioned here or included — the tip kits on the torch parts shelf of this site are 0.030 and 0.035 in. And the listing is written as sales copy rather than specification, to the point of a bullet that invites you to color all your clients impressed with the precision and arc control. The specification that matters, 0.023 in on a ten-pound spool of ER70S-6, is in the title.

The questions welders ask

Why does a fine wire matter so much on sheet?

Because the current follows the wire. A thinner wire carries less current at a given feed speed, which means less heat into the panel — and on 0.8 or 1 mm (0.04 in) car-body steel, heat is what causes burn-through and distortion. This hub’s buying tip puts it plainly: match the diameter to the thinnest metal you weld, not the thickest, because the thin end is where mistakes cost a panel. At 0.023 in this is the only wire in this hub that belongs on a wing or a sill.

Do I need anything else to run it?

Probably, and the listing does not say so. A 0.023 in wire needs a contact tip bored for it — a 0.030 in tip will let it wander and arc inside the tip — and ideally a liner suited to fine wire, because a thin wire buckles in an oversized liner instead of feeding. The torch parts shelf of this site carries 0.030 in tip kits; 0.023 in tips are a separate purchase this page does not mention.

Why is the finest wire the most expensive?

Drawing. Every reduction in diameter is another pass through a die, and a 0.023 in wire has been drawn further, inspected more and is more easily damaged in handling than a 0.035 in one. Ten pounds also goes much further in meters at this size, so the cost per weld is not as high as the cost per spool suggests.

    • 0.030 in is the general-purpose diameter, per this shelf's buying tip
    • The same price as the maker’s 0.035 in wire on this shelf, so diameter is a free choice rather than a cost
    • No tensile figure, no named shielding gas and no copper coating statement

    PGN Bearings ZY-GHM-0902-06, ER70S-6, 0.035 in, 10 lb

    The coarsest of three PGN wires on this shelf, on a listing whose fourth bullet exists purely to state the diameter and the weight clearly.

    EAN
    0760655001301
    • One of three diameters of the same wire on this shelf — .023, .030 and .035 in — so the range covers sheet to section
    • A bullet devoted to stating the diameter and spool weight plainly, "making the key specifications easy to verify before ordering"
    • Carries a different reference format from the maker’s own .023 in and .030 in wires — ZY-GHM-0902-06 against WW-ER70S6-nnn-10LB

    Best for: Heavier fabrication, bought from a maker that offers the same wire in three diameters

  • VEVOR ER70S-6 MIG welding wire, 0.035 inch, on an eleven-pound spool

    VEVOR ER70S-6, 0.035 in, 11 lb

    The coarser of the two VEVOR wires on this shelf, in the larger spool — and the one whose listing drops the tensile figure its own stablemate publishes.

    EAN
    0840349946337
    • Eleven pounds rather than ten, for a small increase over the brand’s 0.030 in spool
    • States the deoxidiser argument — higher manganese and silicon for dirty, oily or rusted steel
    • Does not publish the 490 MPa tensile figure that the same maker’s 0.030 in listing gives

    Best for: Thicker section and structural work, where 0.035 in lays metal faster than 0.030
