美国采购需求：便携式激光打标机，光纤激光打标机，激光雕刻机，珠宝激光雕刻机，光纤激光机，二氧化碳激光打标机

I'm looking to purchase a jewelry soldering machine along with an engraving machine. Could you provide detailed specifications for both machines, including their capabilities, features, and any available options for customization? I'm particularly interested in understanding the soldering technology employed, as well as the engraving precision and software compatibility. Additionally, I'd like to know about the production lead times, warranty information, and pricing structures for bulk orders. If you have any recommendations based on what's popular in the industry or new arrivals, that would be very helpful. Also, please include any information regarding after-sales support and maintenance services that you provide. Looking forward to your response!
