- Hardware automatic welding supporting production line

Core Advantages
Uniform Pneumatic Key Clamping, No Thin Plate Deformation
Multiple independent cylinders press synchronously with even clamping force. 0.3-5mm thin stainless steel won't wrinkle during welding; weld flatness improves by 60% compared with single-point clamping.
Water-Cooled Copper Backing Strip + Back Shielding Gas, No Oxidation Blackening
Standard water cooling backing plate with optional back argon protection. Weld surface requires no grinding and polishing after welding, greatly reducing post-processing labor cost.
Integrated PLC Digital Control, One-Click Parameter Storage
Touch screen to adjust welding speed, torch height and delay start/stop digitally. Multiple sets of workpiece programs can be saved for quick model change without repeated debugging.
