Details Introduction
CTM-15BC String Welding Machine is an automated production equipment dedicated to weld BC cells to strings; compatible with 156–210mm (3BB-20BB) solar cells. It produces 156–210mm BC cell strings (including half-cell and third-cut formats). Integrated with advanced automation technologies—such as PLC control, servo systems, and machine vision—it enables fully automated processing from cell loading to finished string output.

What is the Warranty Period of ChinTiyan New Energy?
1.One year standard warranty from the date of completion installation & commissioning for the Full/Semi-Automatic Solar PV Module Production Line, or 13 months from the date of shipment whichever is earlier.
2.For the BOM List of Raw Materials for Full/Semi-Automatic Solar Panel Production Line, the Warranty Period is usually Six Months, especially Flux, Heating Oil and some other Chemicals and Dangerous Materials.
3.Free warranty for One Year (including Labor and Material fees, excluding Man-made Damage). Any losses caused by human misuse, abuse or improper maintenance are not covered by the warranty. Maintenance fees will be charged appropriately outside the warranty period.
What are the Main Differences Between Full-Automatic and Semi-Automatic Solar PV Module Production Line?
1.For the Full-Automatic Solar PV Module Production Line, there are more Automatic Solar Machines and Equipment in the Production Line, which could surely save more labors.
2.In the Full-Automatic Solar PV Module Production Line, there are also many Automatic Conveyors and Transmission Lines, which could help to transfer the Raw Materials from one process to the next process; But in the Semi-Automatic Solar PV Module Production Line, it needs labors to carry the unfinished Solar PV Modules from one process to the next process.
What is the Payment Terms of the Purchasement in ChinTiyan?
1. Once the Clients confirm the Final Prices of all the solar making machines and equipment, ChinTiyan New energy will send the Performa Invoice (PI) to the Clients. Clients should arrange 40%T/T deposit as the Down Payment, then ChinTiyan factory will start manufacturing all the Machines and Equipment.
2. During the Manufacture Process, Clients can come to ChinTiyan factory to inspect all the Solar Machines and Equipment if required. After inspection, Clients should arrange the rest 60% Balanced Payment Before Delievery or Shipment. ChinTiyan factory start to pack all the Solar Machines and Equipment, and deliver them to Clients. If Clients could not come to China for the inspection, ChinTiyan factory could send the Videos and Photos of all the Solar Machines and Equipment for Clients as reference.
What is the Policy of Installation, Commissioning & Training Services of ChinTiyan New Energy?
1. Workers and Technical Engineers of the Purchaser can come to ChinTiyan’s factory to get the most Professional One-by-one Training.
2. ChinTiyan New Energy may also send Engineering Team to the Purchaser's factory to train their workers during operation.
3. Remote training through Internet tools like Team-Viewer, Google Meet or other instant communication software.
