Battery Manufacturing EquipmentWinAck M80ZT manual tab-to-terminal resistance welder
The WinAck M80ZT is a manual, pneumatically driven resistance welder for joining battery tabs to terminals. Two opposed heads press from both sides and an inverter DC supply delivers up to 8000 A short-circuit current. It handles nickel, stainless-steel and copper tabs from 0.05–0.80 mm, one joint at a time.

Tab materials, thickness and head access
WinAck lists pure nickel, stainless steel and copper tabs from 0.05–0.80 mm and describes head-to-head welding, copper tab to terminal included. Ask whether that range applies to one tab or to the whole stack. Send the terminal geometry, material, plating and surface condition. The two heads have to reach both sides of the joint and clamp the parts the same way every time.
The head is pneumatic and the parts are handled by hand. WinAck gives 0.5–0.8 seconds per welding operation, which covers the weld itself. Loading, positioning, checking and unloading add to each cycle. Look at electrode access on your own fixture before planning output or operator numbers.

Supply limits and pulse control
The catalogue gives an 8000 A maximum short-circuit output, 15 kVA maximum transformer output and a 4 kHz inverter frequency. These figures set the ceiling of the supply. The current through your joint depends on contact resistance, force and the parts. The DSP controller runs up to three pulses in constant-current or constant-voltage mode. Ask for the recipe settings, feedback signals and allowed electrode force for the head you will receive.
Weld time is adjustable from 1–20 ms with a setting accuracy of 0.1 ms, separate from the per-operation time above. Run your own tab and terminal samples and record pulse shape and repeatability. Guard against pinch points, heat, spatter and the hazards of a live cell in the fixture, even though the welding voltage is low.

What a good tab joint must pass
Welding needles are 3 mm as standard with custom sizes available, and cooling is forced air. Ask for tip material, shape, dressing interval and replacement method for copper, nickel and stainless joints. Tip wear changes contact and heating, so log the tip condition alongside each acceptance sample.
Agree limits for joint resistance, peel or pull strength, visible defects and any temperature rise at the terminal or cell. Judge strength on sections of your own material stack. Power is 380 V ±10%, 50/60 Hz, and compressed air runs at 0.4–0.8 MPa. Clarify guarding, fixture controls and who provides service under WinAck's warranty.
A weak tab weld later appears as high internal resistance, which the cell measurement page shows how to measure. The guide to comparing supplier responses helps keep pulse settings separate from joint results.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Can opposing heads reach the joint? | The welder presses head to head and parts are placed by hand. | Approve terminal access, fixture and electrode-tip drawings. |
| Which pulse mode qualifies the stack? | The catalogue lists 8000 A maximum short-circuit output and up to three pulses. | Trial your materials and record current, time and force. |
| What is a good tab weld? | The catalogue lists materials and thickness but no joint strength or resistance values. | Specify resistance, strength, defect and thermal limits. |
