Welding machine outputs (compatible with TIG/MIG/arc welding).
PCB etching equipment, automated production lines.
Chemical plants, wastewater treatment facilities.
Key Advantages vs. Standard Welding Cables
Parameter
Acid-Resistant Double PVC Cable
Standard Welding Cable (e.g., RHW/RHW-2)
Chemical Resistance
Excellent (pH 3–12)
Limited (rubber degrades in chemicals)
Insulation Layers
2 (color-coded)
1 (single rubber/PVC)
Voltage Rating
Up to 1 kV
≤ 600V
Lifespan
15+ years (fixed installations)
3–8 years (subject to environment)
Cost Efficiency
Higher upfront, lower TCO
Lower upfront, higher replacement costs
Procurement Guidance
For corrosive environments (e.g., electroplating): Specify "Double PVC Insulated, Acid-Resistant Welding Cable" with orange outer sheath.
For heavy-duty welding: Ensure cross-sections ≥ 50 mm² (for 300–500A welders).
Certification note: Verify UL/CSA marks if required for North American projects.
Example Part No.:
PVC-ARWC-70-25 (25mm², 70°C rating, orange)
