WeldWorld already features 137 creator-shot works

UF20B uses brand-new quality supercapacitors (500k cycles) for sustained welding power: steadier (millisecond dual-pulse, no heat or blown tubes in continuous work), longer-lasting (real-time storage, +100% endurance), stronger (10500W, welds 0.4mm, handles copper) and durable.

A color screen locks in six core factors for thousands of fine settings; boosted by a smart hand pen (40cm, removable alumina-copper pins) and a foot switch.

For power-tool and appliance repair, small-to-medium pack assembly, coin cells, phone repair and metal joining.

Aluminum-and-plastic body, 181×95×80mm, about 1.25kg.

Highlights

01Only brand-new supercapacitors

No refurbished or imported salvaged capacitors — brand-new automotive-grade supercapacitors run at rated voltage for double safety and stability.

0210.5kW · 1750A · welds 0.4mm

Millisecond energy plus dual-pulse: Ni-plated/steel 0.4mm, pure nickel 0.25mm, copper 0.15mm (with flux).

0315A high-current fast charge

The supercapacitor recharges in seconds, so continuous welding never waits or fades.

04Three welding modes

AT auto mode (smart sensing, batch work) · MT hand-pen mode (precise triggering, fine work) · MT foot-switch mode (hands and feet together).

How thick can it weld

Nickel-plated steel strip
0.4mm
Pure nickel strip
0.3mm
Copper strip
0.2mm
Stainless strip
0.4mm

Lab maximums; results vary with material batch and conditions, so test on scrap first.

Putting everything into every welder, so it is worthy of the people who use it — that is AWithZ's baseline.
