I'm interested in learning more about the pricing details for your laser welding machines. Specifically, could you provide the cost for one unit, along with any relevant specifications or features that might be included? Additionally, if there are any options for bulk purchases or potential discounts, I'd love to hear about those as well. Understanding the lead time for delivery and any warranty or after-sales support would also be appreciated. Looking forward to your detailed response!
