Rogue machines feature a digital display, weigh less than 10 kg and, depending on the model, offer maximum welding outputs of 150A, 180A or 200A. The series includes four models with MMA and TIG outputs and a Live TIG arc start function (Rogue ES 150i, 180i, 180iPRO and 200i PRO). It also includes two TIG/MMA models, Rogue ET 180i and 200iP PRO, that feature a high frequency arc start function for applications that require non-contact arc starts or for added convenience.
A fibreglass-molded housing is built to withstand impact, and the weather resistant, IP23S rating makes Rogue suitable for use in tough applications. Users include mechanical contractors and those in general fabrication, maintenance and repair, rental, process pipe, food/beverage, farming and home workshops.
All machines connect to 230V mains power. Rogue PRO models run on 90 – 270V main power, enabling users to work in a wide variety of locations. Flexible automatic input voltage compensation ensures a steady welding arc throughout the entire input power range, which makes them ideal for situations with dirty power and generator power, which often fluctuate. PRO models also feature power factor correction.
All Rogue machines feature adjustable hot start and arc force control. The hot start function increases current beyond the set value for a few milliseconds to help establish the arc. It especially helps with low-hydrogen electrodes, which can be notoriously difficult to start. Arc force control increases amperage when the voltage drops below a preset threshold. As a result, operators can hold a shorter arc length without the electrode sticking, which is beneficial when welding in narrow gaps, in corners and out-of-position.
Rogue ET 180i and 200iP PRO include full-featured digital TIG controls for gas pre-flow, arc start current, end current, gas post-flow and HF (non-contact) or LiveTIG arc starts. Tipping the scales at 8.7 kg and 9.6 kg, respectively, Rogue ET 180i and 200iP PRO units are one-third lighter than competitive inverters in its class. Both units measure only 403 x 153 x 264 mm but deliver a maximum TIG output of 180A (180i) and 200A (200iP PRO) at 25% duty cycle and a stable TIG arc down to 10 amps. They come with accessories including an SR-B 26 TIG torch with 4 m cable and 3 m work cable, both with 50 mm dinse connections.
The 200iP PRO version has a pulsing feature with frequency adjustable from 0.2 Hz to 500 Hz. Stainless steel fabricators and those working with thin metals or other heat-sensitive applications use pulsed DC TIG to control heat input, narrow the weld bead profile and increase travel speed. A slow frequency, such as 1 pulse per second, helps welders establish a good rhythm for adding filler rod.
