New Renegade series of MMA/TIG inverters from ESABESAB Welding and Cutting Products is launching its Renegade Series inverters for advanced DC TIG and MMA/Stick welding. Combining power with low weight and location flexibility, the Renegade Series has three models: Renegade ES 300i for MMA and Live TIG, Renegade ET 300i for MMA and TIG with high frequency (HF) or Lift TIG arc starts and Renegade ET 300iP, which adds controls for pulsed TIG welding.

Renegade ES 300i weighs only 15.5kg and Renegade ET models weigh 17kg. All models measure just 460mm by 200mm by 320mm, giving them the smallest footprint among their competitors and simplifying trolley maneuvers when configured as a water-cooled system.

With Renegade’s clever handle design offering built-in storage and security for the welding cables, operators can quickly pack up and go by wrapping the cables around the handles and locking them in with a dedicated shoulder strap. Its three-handle roll cage design allows lifting with one hand, both hands, via shoulder strap or by crane. The welder’s rugged composite casing was designed to withstand the roughest environments and more mechanical impact than any other machine on the market.

With outstanding power and reach, Renegade runs 300 amps at 40 per cent duty cycle with mains and welding cables up to 100 m and has excellent multi-voltage capabilities. The ET 300i and ET 300iP connect to 230 V 1-phase power and 230V to 480V 3-phase power (both +/-10 percent) with auto-sensing functionality and no rewiring required. The ES 300i connects to 230V to 480V 3-phase power +/-10 per cent with auto-sensing functionality.

Martin Freibergs, Business Product Manager Industrial/Light Industrial Product Systems, ESAB, says: “Renegade is a next-generation work shop and field welding machine combined into one, offering more power and a design that’s easier to move around any jobsite. When Renegade can’t be located next to the work piece, its strong output enables the use of long welding cables and longer work leads.”

Maximum MMA capabilities

Renegade has an amperage output range of 5 to 300amps and can weld with MMA electrodes up to 6mm. It has gouging capabilities with carbons up to 4.8mm diameter, making it the most powerful welder in its weight class. Renegade’s MMA performance is enhanced by built-in intelligence for optimising starts and stops and controlling arc stability.

Freibergs says: “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. For welding with cellulosic electrodes, Renegade ES 300i provides a higher arc voltage and the ability to hold longer arc length. It produces a soft arc and impeccable starts and stops using E6010 electrodes.”

Other MMA performance features include semi-synergic 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 get a crisp and well-controlled arc or a softer arc with less spatter, tailoring the arc for different electrodes, applications and operator preference. Preferences can be stored in one of three memory functions.

Freibergs says: “Renegade has an intuitive digital readout display that makes it easy to set parameters and read them from a distance in any light. A remote amperage control with a digital display extends operator range by providing extreme accuracy over long distances.”

Advanced TIG functions

Renegade ET 300i and ET 300iP provide HF arc starts for applications requiring non-contact arc starts and Lift TIG for arc starts without HF. They also provide adjustable gas pre- and post-flow, adjustable upslope/downslope, 2- and 4-stroke trigger functionality, offer a remote foot pedal compatibility and include a water-cooled option. Renegade ET models convert from a water-cooled system to an air-cooled portable system in minutes, and conversion does not require tools.

Renegade ET 300iP provides a pulsed TIG output, which can be used to improve weld puddle control, control the weld bead profile, reduce heat input and increase travel speeds. It has a pulse frequency reaching 999Hz or pulses per second (PPS) and a peak pulse width (or duration) adjustable between 10 and 90 per cent. Stainless steel fabricators and those working with thin metals or other heat sensitive applications use pulsed TIG to reduce heat input, narrow the weld profile and increase travel speed.

Freibergs says: “Renegade ET 300iP enables tailoring the pulsed DC TIG welding arc to the application, which is especially useful when welding thin material such as stainless steel pipes in the food and process industry.”
