The only gasless wire here — and it never mentions polarity
YESWELDER E71T-GS gasless, 0.030 in, 2 lb
The only flux-cored wire in this hub, and its listing says nothing about the polarity change this hub’s own introduction warns about.
This is the only wire in this hub that works without a gas bottle, and that single property decides who should buy it. Outdoors, in a draft, or on a machine that has never had gas on it, solid wire under gas simply does not work — the shielding blows away and the weld goes porous. A self-shielded flux-cored wire carries its own shielding in the flux, which is why it is the farm-gate and field-repair wire.
The listing is sound on what the wire does: all positions, over light rust and mill scale, low spatter for its type, a slag that lifts, and an ABS spool built for a wire feeder rather than a bare coil. Two pounds is a small spool, which suits a machine that only occasionally runs gasless.
What it does not mention is the thing this hub’s introduction singles out. Self-shielded flux-cored wire normally runs with the polarity reversed — electrode negative, where solid wire runs electrode positive — and a machine left on its solid-wire setting produces a fierce, wandering, spattery arc that gets blamed on the wire every time. Nothing on this page says it. It is the first thing to check in your machine’s manual before the spool goes on.
