美国采购需求：电池焊接机，激光焊接机

We are currently in the market for a versatile multi-purpose laser welder capable of handling both lithium battery tab welding and aluminum battery box welding. One of the key features we're looking for is a programmable engraving option, which would greatly enhance the machine's functionality for our needs. We're specifically interested in a 2000W model that encompasses all these capabilities. Could you please provide detailed information on the machines that meet these criteria? Additionally, since we are based in the US, it would be helpful to know if you have stock available here for a quicker turnaround. Looking forward to your prompt response!
