Portable Renegade MMA/TIG welder delivers more powerESAB Welding & Cutting Products is launching the Renegade ES 300i for MMA (SMAW) and LiveTIG (GTAW) welding. This inverter-based MMA/TIG machine offers extreme power in a compact format: it weighs 15kg, measures 460x200x320mm and produces a maximum output of 300A at 40 per cent duty cycle.

Easy-to-grab front, rear and top handles give the operator maximum flexibility for lifting the machine, and a padded strap can be attached for carrying the machine over one shoulder. Operators can easily pass obstacles, climb stairs, pass through manholes and lift the unit onto racks, making the Renegade an excellent welding machine for applications such as repair and maintenance, ship and offshore yards, construction, pipe welding and heavy fabrication.

Martin Freibergs, Business Product Manager for Arc Equipment at ESAB, comments: "Renegade is a next-generation field welding machine, offering more power and a design that is easier to move around any job site. When Renegade cannot be located next to the work, its strong output enables the use of welding cables and work leads up to 100m, and a remote amperage control extends the operator's range by providing extreme accuracy over long distances."

For added location flexibility, automatic voltage detection enables the machine to accept three-phase primary power input ranging from 230V to 480V +/-10 per cent.

Renegade's ergonomic handle design provides built-in storage and security for the welding cables so operators can quickly pack up and go by wrapping the cables around the handles and locking them in with a dedicated shoulder strap. Renegade's rugged composite casing was designed to withstand rough handling, harsh environments and more mechanical impact than any other machine on the market.

Power and performance

Renegade has an amperage output range of 5-300A, including LiveTIG for TIG welding where HF ignition cannot be used. Renegade can weld with electrodes up to 6mm and has gouging capabilities with carbons up to 4.8mm diameter, making it the most powerful welder in its weight class according to ESAB.

Performance features include Adjustable Hot Start, a process that provides optimal energy during the starting sequence, improves strike performance and reduces sticking. Similarly, the Adjustable Arc Force function enables the operator to adjust the arc characteristics to find the right balance between arc control, penetration and weld bead appearance. Preferences can be stored in one of three memory functions.

Freibergs concludes: "As a next-generation inverter, Renegade provides state-of-the-art weld control for a more stable arc, less spatter and improved arc starts and stops."
