J3S Steel & Stainless Wire Butt Welder
Transform your welding operations with the JS Series Micro Weld Butt Welders — engineered for durability, performance, and consistent, high-quality welds on solid steel, stainless, and titanium wire and rod up to .5 in (12,7 mm) across the range. The J3S is the finest-capacity model in the five-model line, welding solid steel from .020 in (0,50 mm) to .080 in (2,03 mm). An extra heavy-duty transformer supports continuous processing, while solid-state 99-step SCR heat control delivers the fine, repeatable heat stainless and titanium required. Foot-actuated dual-action clamping and upset keep both hands free, and selectable 120V, 240V, or 480V power simplifies installation.

Rejoining stock on payoff and take-up lines to keep a running line fed
Stainless and titanium wire and rod joining where a clean, full-strength butt weld is required
Real-World Benefits
- Extra heavy-duty transformer supports continuous processing of steel wire and rod without duty-cycle stalls.
- Solid-state 99-step SCR heat control delivers fine, repeatable heat selection — important for consistent results on stainless and titanium.
- Foot-actuated, dual-action clamping and upset keep both hands free for wire handling and give a consistent, operator-independent upset.
- Selectable 120V, 240V, or 480V single-phase power makes the machine easy to drop into most shop services.
- Mobile 4-wheel truck lets the station move to the line; anneal, vise, shear, and grinder options handle prep, weld, and finish.

Comparison to Similar Models
“S” models are the ferrous line — the JS Series — welding solid steel, stainless, and titanium wire and rod up to .5 in across the full range. This is the counterpart to the non-ferrous JC line (copper/aluminum) and the flat-stock JSF line, all built on the same J chassis with the same foot-actuated upset and SCR heat control.
The J3S is the smallest-capacity JS model, welding solid steel from .020 in to .080 in (0.50–2.03 mm) — the finest steel range in the line. Step up to the J4S (.040–.160 in), J5S (.060–.250 in), or J6S (.187–.375 in) as your stock grows. For non-ferrous wire choose the JC line; for flat strip choose the JSF line.
Best For
Shops running the lightest solid steel, stainless, or titanium wire (.020–.080 in) — fine springs, wire forms, and fasteners — that want the smallest, most economical, easy-to-handle JS-Series welder.
