Product Advantages
High Weld Straightness
Linear guide movement ensures straight welding track, no weld deviation, neat weld bead for subsequent polishing.
Pneumatic Firm Clamping
Double-side pneumatic pressing to eliminate plate gap, avoid welding penetration defect, stable for thin & thick plate welding.
Adjustable Welding Torch Height
Manual/electric torch lifting adapts to different plate thickness and welding processes.
Integrated Frame Structure
Whole frame stress relief treatment, no deformation after long-time continuous operation.
Easy Operation
Simple control panel, one-key start for automatic welding, lower requirement for welder skill.
Matching Equipment
- Adjustable welding turning rolls for circular girth welding
- Heavy-duty welding positioner for head overturn welding
- Automatic welding manipulator for multi-angle welding operation
- Welding power source to match TIG/MIG welding process
- Welding flux recovery machine for workshop cleaning
