Mini Circle Welder

Mini Circle Welder (MCW)

The Mini Circle Welder is designed for applications such as wind tower brackets inside of wind power towers and small tubes of boiler tube sheet.

Features:

LED screen shows the exact travel speed
Welds 1.18″-3.94″ (30-100 mm) diameter
Adjustable crater fill
The travel speed is controlled by a microcomputer to achieve precise rotation, so the programmed weld length is consistent
When welding is stopped, the built-in automatic crater fill function improves the weld quality
Working position setup is simple with provided torch adjustment device
After welding starts, the machine will weld one turn and then automatically stop
After one cycle of automatic welding is completed, the machine will weld in the opposite direction to prevent cable twisting
When using a collet type centering device, the operator turns the carrying handle to secure the machine to the weldment
If machine is used with the optional 3-jaw chuck, the above statement does not apply
An 18 volt, 4.0Ah rechargeable battery powers the machine
