AWithZ Spot Welders

Pioneer & leader in compact portable spot welders | Spot welders only, done more professionally

How to choose between the three series

AWithZ welders come in three series. Handheld H series (e.g. H1, H2, HF7): welds up to 0.3 mm max in many materials — pure nickel, nickel-plated, stainless steel, steel, iron, red copper and more. The lightest and most portable, suited to occasional use such as home tasks, field repairs and personal DIY. Universal U series (e.g. UF20B, UK3, UK1): welds up to 0.7 mm max in the same range of materials. Balancing portability and power, it suits more frequent use and thicker welds, widely used for 18650/21700/32140 pack DIY and nickel conversion on phone batteries. Professional P series (e.g. P60F, P120D): welds up to 2 mm max; a professional high-power welder with up to 69200KW, handling pure nickel, nickel-plated, stainless steel, steel, iron, red copper and more. The P series has the highest power and welding capability, suited to large prismatic cells / copper / aluminium-to-nickel welding, thick pure nickel, nickel-plated, stainless, steel and iron, and hard-to-weld copper / aluminium. It is widely used by small factories, repair shops, R&D labs and professionals — individuals and businesses who need high welding precision, thick or difficult materials and heavy daily use.
