**Features:**
The MZ7 automatic submerged arc tractor and power source together form an advanced automatic submerged arc welder. It is ideal for butt joints, lap joints, and corner joints in medium-to-thick steel structures. It can weld various materials such as carbon steel, low alloy steel, stainless steel, and heat-resistant steel.
(1) The front and rear wheels of the tractor move simultaneously, providing stable movement and a wide welding range, supporting wire diameters from Ф3.0 to Ф6.0 mm.
(2) Easy adjustment with an integrated rotating head and adjustable welding torch.
(3) The beam can rotate and lift for flexible operation.
(4) The flux container’s turning and fluctuation angle can be adjusted for optimal welding conditions.
(5) The wire feeding mechanism features an alignment structure, ensuring smooth and stable wire feeding with strong pulling force.
(6) A print motor is used for both wire feeding and movement, offering low power consumption and long service life.
(7) Supports MMA and gouging welding.
(8) Built-in welding expert database allows saving up to 30 sets of self-defined parameters.
(9) All-digital LCD menu for easy access to functions and data, enhancing user experience.
