Q403-1-30 - Heavy Duty MIG Contact Tip, 0.030 in, 25-Pack

High-Performance Heavy Duty Contact Tips

The ESAB Q403-1-30 is a premium heavy-duty contact tip designed for professional MIG welding operations. Engineered to accommodate 0.030-inch (0.8 mm) welding wire, these tips are manufactured with tight tolerances to ensure optimal electrical conductivity and arc stability. The heavy-duty designation indicates a robust construction capable of enduring higher amperages and longer weld cycles without premature failure, making them an excellent choice for industrial fabrication environments.

Consistent wire feeding is critical for quality welds, and these contact tips feature a precision-drilled bore that minimizes friction while maintaining positive electrical contact. This design helps prevent micro-arcing inside the tip, which can lead to burn-backs and erratic arc performance. By maintaining a stable arc, welders can achieve cleaner beads with less spatter, reducing post-weld cleanup time.

Supplied in a convenient pack of 25, this SKU ensures that welding stations remain stocked and operational. Frequent tip changes are a reality in high-volume welding, but the extended life of these heavy-duty tips combined with the bulk packaging offers excellent value and operational efficiency. Whether used in automotive repair, structural steel, or general manufacturing, these contact tips provide the reliability required for consistent production.

Compatibility is key in MIG consumables. These tips are designed to fit standard heavy-duty diffusers and MIG guns commonly used in the industry. The copper alloy material provides superior heat dissipation, keeping the tip cooler during operation and preventing the wire from fusing to the tip during stops and starts.
