Lincoln KP3801 CarbonElite™ Hollow Gouging Electrodes (50 Pack)
ELITE PERFORMANCE
CarbonElite™ arc gouging carbon electrodes are made of proprietary composition to deliver high efficiency metal removal. The copper coated carbon's offer excellent arc stability and generate less heat for a controlled melt off rate. Available in pointed, jointed, flat and hollow electrode types for use in numerous semi-automatic or automatic applications.
- Premium synthetic graphite composition extends electrode life to maximize metal removal
- Full copper coating improves arc stability and reduces heat generation
- Consistent melt-off rate for smooth, uniform grooves
- High density formula increases durability
Typical Applications:
- Removing defective welds
- Removing surface welds for re-surfacing
- Preparing joints for welding
- Backgouging base material to allow for a full penetration weld deposit
