10 x Cast Iron Electrodes MTC MT-NiFe 2.5 / 3.2 mm Cast Iron Welding

10 x Cast Iron Electrodes MTC MT-NiFe 2.5 / 3.2 mm Cast Welding

• Quantity: 10
• Alternating current (AC): lowest heat input, favorable for filler pass welding
• Positive pole: higher welding speed, lower penetration, higher bead reinforcement
• Negative pole: pulsating arc, deep penetration, good side-wall fusion, flat welds
• Special instructions: Universally applicable rod electrode for repair welding on cast iron parts. Weld short beads (30 - 50 mm), immediately peen weld beads well to relieve stress. Certain properties can be achieved by selecting the appropriate polarity when welding with direct current (DC).
• Standard designation:
  DIN 8573:                   E Ni - BG 1
  EN 1071:                    E C Ni CI 1
