IV. Product Advantages
Excellent Process Performance
Stable arc combustion with low spatter, reducing post-welding cleaning work;
Beautiful weld formation with smooth transition, no undercut or incomplete fusion defects;
Low sensitivity to porosity, suitable for all-position welding (flat/vertical/horizontal/overhead welding), and wide current range.
Reliable Quality & Safety
Low phosphorus and sulfur content, reducing the risk of cold brittleness and hot cracking;
Copper coating for protection, extending storage life and ensuring welding electrical conductivity;
The entire process complies with international standards, supported by multiple certifications.
Strong Adaptability
Multiple diameter specifications available, suitable for welding from thin plates to thick plates;
OEM customization supported (packaging/marking) to meet personalized needs.
V. Application Scenarios
Vehicle Manufacturing: Welding of automobile bodies, frames, and truck compartments, withstanding vibration and impact;
Engineering Construction: Load-bearing beams of bridges, steel structure workshops, and steel frames of high-rise buildings;
Heavy Equipment: Welding of thick plates such as construction machinery (excavators/loaders) and ship decks;
General Manufacturing: Splicing of container bodies and welding of building steel structure connectors.
VI. Welding Operation Points
Workpiece Preprocessing: Thoroughly remove oil, rust, and moisture from the workpiece surface before welding to avoid porosity in the weld;
Gas Requirements: CO₂ gas purity should be ≥99.5%, and preheating and drying are required to prevent hydrogen-induced cracking;
Environmental Control: When wind speed exceeds 2m/s, windbreak sheds or wind deflectors should be used to ensure the gas shielding effect;
Parameter Reference: For 0.8mm wire, the recommended current is 80-120A; for 1.2mm wire, the recommended current is 140-200A (adjustable based on test welding).
VII. Packaging & Delivery
1. Packaging Method
Basic Packaging: Spool + Plastic Film + Color Box + Pallet;
Customization Service: Packaging specifications can be adjusted according to customer needs.
2. Delivery Details
Delivery Cycle: Regular specifications are shipped within 8-25 days after order confirmation;
Sample Policy: New customers can apply for free samples for testing.
VIII. Procurement & Services
Price Advantage: Direct supply from the source factory, supporting wholesale/discounts, and lower costs for bulk procurement;
