WELDING PARAMETERS
PREHEATING
None required. Minimal during cold weather operations to remove condensation.
CAPABILITY
Horizontal, vertical (sidehand)
POWER/TIMER
1200 to 1400 amps/0.9 to 1.1 seconds
APPLICATION RATE
Up to 250 Tuffstudds per hour; coverage up to 4ft2 per hour (0.4 m2/h)
SPACING
For normal abrasive conditions, install in a close packed staggered pattern with about 70 Tuffstudds per square foot (700/m2). For severe abrasive conditions, install in a close packed staggered pattern with about 76 Tuffstudds per square foot (860/m2). More open spacing is not recommended for most applications.
