Contact Tip [Heavy Duty] For Tweco SP4 MIG Welding Torches (25 Pack)

Engineered for extreme industrial applications, our Heavy Duty (HD) 2.0mm contact tip is built specifically for the Tweco SP4 series. This specialized consumable is designed to manage the massive electrical and thermal loads required for feeding 2.0mm heavy gauge wire, making it the go to choice for high deposition welding and heavy plate fabrication.

The HD (Heavy Duty) specification signifies a robust copper construction with enhanced wall thickness. This provides the necessary thermal mass to dissipate intense radiant heat, maintaining bore integrity and preventing "key holing" during continuous duty cycles. If your operations involve heavy infrastructure, mining equipment repair, or large scale structural engineering, these tips provide the arc stability and longevity required for the toughest environments.

Sold in packs of 25 - great for everyday use or stocking.
