The welder supports both 110V and 220V power inputs, providing flexibility for various working environments. This feature ensures that the welder can be used with standard household power or industrial power sources, making it suitable for a wide range of applications.
The large LED display enhances the welder’s usability by providing clear and intuitive controls. It allows users to easily adjust settings such as voltage, current, and wire speed, ensuring precise control over the welding process. The display also provides real-time feedback on the machine’s performance, helping users make immediate adjustments as needed.
With a maximum output of 250 amps, the AZZUNO welder can handle heavy-duty welding tasks. This high amperage capability makes it suitable for welding thicker materials and for extended welding sessions without compromising performance.
Despite its extensive features, the AZZUNO Aluminum 250Amp MIG Welder is designed to be portable. Its compact design and sturdy build make it easy to transport between job sites. The machine’s construction ensures durability and is capable of withstanding the rigours of daily use in various working environments.
The welder comes with a range of accessories to enhance its functionality. It includes a MIG torch, electrode holder, work clamp, gas hose, and a spool gun for aluminium welding. The compatibility with different welding accessories and consumables makes it a versatile tool for various welding projects.
Gas Metal Arc Welding (GMAW), commonly known as MIG welding, is one of the most widely used welding processes. It involves feeding a continuous solid wire electrode through a welding gun into the weld pool, joining the two base materials together. A shielding gas is also sent through the welding gun to protect the weld pool from contamination.
Gasless Flux Core Welding
Flux Core Arc Welding (FCAW) without gas shielding, also known as gasless flux core welding, utilizes a tubular wire filled with flux. The flux generates a shielding gas and slag to protect the weld pool, making it suitable for outdoor welding where external shielding gas might be blown away.
Shielded Metal Arc Welding (SMAW), commonly referred to as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux. An electric current creates an arc between the electrode and the base material, melting both to form the weld pool.
Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode to produce the weld. Lift TIG welding allows for precise arc control by initiating the arc with a lift motion, eliminating the need for high-frequency starting.
Spot welding is a resistance welding process used to join overlapping sheets of metal at small points by applying pressure and heat from an electric current.
Spool gun welding is a variation of MIG welding that uses a spool gun to feed the wire directly to the welding torch, reducing wire tangling and improving feed consistency, especially for aluminium welding.
