Battery Spot Welding Service in Sydney

Does anyone know of a service in Sydney that can spot weld onto batteries?

I have a now dead 26500 Li-Ion battery I wish to remove a connector and polyswitch fuse from and apply to a new battery.
I only have a solder iron, and not a particularly special one at that, basic Bunnings/Supercheap one.

The device it's going into is worth a few hundred, so replacing it overall is not ideal, and i would rather just do the battery, so if anyone knows of a service, preferably North West/Western Sydney, but can travel regardless, it would be greatly appreciated, Google has given me nothing but actual spot welding products.

    Is this for your Tesla?

      Yeah, I had it running on AAAs initially, thought I would boost it up to 26500.

    I would contact Battery World or the company below. Though you may have to purchase the battery from them.

    Looks pretty easy to jerry-rig if you fancy giving it a go yourself: https://www.youtube.com/watch?v=o1NFbchHeM8

    I've been eyeing off this battery spot welder from aliexpress for $82 delivered

      That's the one I got. Works really well (does .2mm Nickel easily…most don't). The build quality internally is a bit dodge so there are some remedial bits to do to make it more resilient (lookk at 500W Spot welder on youtube). The big cables are soldered directly onto the battery and are poorly supported…can detach is treated roughly.
