Description

The Tradeweld MMA120 DC Inverter Welding Machine combines portability, performance, and rugged reliability in a single compact package. Built for both beginner and experienced welders, this lightweight MMA welder delivers consistent arc stability across a wide amperage range of 20 to 120 amps. With a 60% duty cycle and a durable fan-cooled body, it is engineered for demanding work in garages, workshops, and field environments. Its robust inverter technology ensures high efficiency and lower power consumption, while the included accessories let users get started immediately. Whether you’re fabricating steel frames or completing maintenance tasks, this welder provides exceptional control and output.

Reliable 60% duty cycle supports extended welding sessions with consistent output: Designed for productivity, this unit operates at a 60% duty cycle, meaning it can weld continuously for longer stretches without risking performance drop. The high thermal tolerance ensures arc stability across various electrode types, making it a dependable option for structural repairs, fabrication work, and general maintenance welding.

Full amperage control from 20 to 120A for tackling a wide range of welding tasks: The MMA120 gives you the flexibility to work on thin sheet metal or heavier gauge materials by offering variable output from 20 to 120 amps. The wide amperage range allows for accurate adjustment depending on your electrode type and project demands, giving precise control and consistent bead quality every time.

Advanced inverter technology reduces power usage and increases efficiency: Thanks to modern inverter circuitry, this welder provides high-frequency switching and low energy consumption, ideal for users working off limited power sources. It produces cleaner, smoother arcs and better starts compared to traditional transformer welders, resulting in less spatter and easier clean-up after welding.

Lightweight and compact with integrated fan cooling for greater portability and endurance: Weighing far less than conventional welders, the MMA120 is highly portable and perfect for mobile jobs or workshop use with limited space. The integrated cooling fan and IP21S protection class ensure that the unit remains cool and safe under load, extending its service life and reducing maintenance needs.

Works with electrodes up to 2.5mm for common stick welding applications: Whether you’re using E6013, E7018, or general-purpose electrodes, this machine accommodates sticks up to 2.5mm, making it versatile enough for steel fabrication, light construction, and general repairs. The 25V output provides solid penetration while maintaining control over heat input and arc behavior.

Includes essential accessories for immediate use right out of the box: To help you get started straight away, the machine comes with a welding cable set, hand face shield, and brush/chipping hammer. These add-ons are ideal for casual users and DIY enthusiasts who want a complete kit without needing to source additional gear.

24-month warranty and strong build quality for peace of mind and long-term use: Built to withstand tough environments, this welder is supported by a 24-month warranty, ensuring you get lasting value from your purchase. The tough outer housing and fan-cooling system make it suitable for on-site jobs and regular use without compromise.

Combining user-friendly operation, energy-efficient design, and reliable welding performance, the Tradeweld MMA120 DC Inverter Welding Machine is a smart investment for hobbyists, tradespeople, and mobile welders alike. Its compact form factor makes it easy to transport, while the wide amperage range and robust duty cycle ensure it can handle everything from quick fixes to full fabrication projects. Whether you’re working in the garage or out in the field, this machine delivers professional-grade results at a competitive value.
