Features:
The MZ7 automatic submerged arc welder and power source together form a complete system that is ideal for butt joints, lap joints, and corner joints in medium-to-thick steel structures. It can be used for welding carbon steel, low alloy steel, stainless steel, and heat-resistant steel. Key features include:
(1) Front and rear wheels move simultaneously for stable operation and a wide welding range (wire diameter: Ф3.0–Ф6.0mm)
(2) Easy adjustment, with an integrated head and adjustable welding torch
(3) Beam can rotate and lift for flexible positioning
(4) Adjustable flux container angle for optimal welding conditions
(5) Wire feeder with alignment mechanism for smooth feeding and strong pulling force
(6) Uses a print motor for both wire feeding and movement, ensuring long life and stability
(7) Supports MMA and gouging welding for versatile applications
