Welding Solutions to Achieve High Quality & High Speed Automation
KOBELCO offers welding solutions package, original welding process integrated with welding robot system and welding consumables
Ultra High Current GMAW welding process
Ultra High Current GMAW welding process (Approx. 2 minutes)
Ultra-high current GMAW welding process provides high efficiency
Ultra-high current MAG welding process provides high efficiency. Double productivity of conventional single arc, and same as tandem arc process.
Spray arc provides low spatter, even at high current
Low spatter and stable arc has been achieved with Ultra high current GMAW process and MX-A100D specially designed for this process.
Deep Penetration
Obtain deeper penetration than conventional process.

Welding Robot ARCMAN™ MP
Welding wire FAMILIARC™ MX-A100D 1.4mmΦ
Welding Power Source SENSARC™ AB500
Tandem Arc Welding System
Features
Tandem welding reduces the cycle time by about 40% compared to single welding.
Advanced Lord Characteristic Control and Synchronous Amplitude Modulation Control function ensures stable arc and lower spatter welding.
Dual Arc Sensor detects the difference in the amperage of the leading and the trailing wire and adjusts the alightment of the leading wire as well as correct the misalignment of the trailing wire during welding. This function significantly improves the welding quality and reduces the need for repair welding.
Efficient Horizontal Fillet Welding with CB controller
Features
Able to achieve high speed horizontal fillet welding with single arc, 6mm leg length at 700mm/min, without undercuts and overlaps. Able to simplify positioner by changing welding position from Flat positon to Horizontal Fillet position.
Able to simplify positioner
Function
Setting arc voltage at vertical and flat member sides independently
Changing weaving direction
Cofigulation
Manupilator: ARCMAN™ GS, ARCMAN™ MP
