Rogue ET180i is a TIG welding machine with HF ignition in direct current (DC) and MMA, built with the latest inverter technologies to guarantee an extremely stable welding arc, ideal for working on iron, stainless steel, brass, cast iron...

The electronic boards of the Rogue ET 201i PRO are protected by a special coating that insulates them from moisture and dust (IP23S protection). The body is very robust and the dimensions are compact, allowing the operator to transport and use this welding machine in the workshop or on site even in adverse environmental conditions.

The Rogue ET201i PRO can generate a maximum welding current of 200A and has a duty cycle of 129 A at 60%; these characteristics make this welding machine ideal for installation, maintenance and light joinery work.

The control panel of the Rogue ET201i PRO is easy to use and the convenient LCD screen allows the operator to accurately view the welding parameters. From the control panel, it is possible to modify the TIG welding parameters to adapt the process to the operator's needs: LIFT or HF trigger mode, pre and post gas, initial and final current, up and down slope, 2T or 4T.

If you use the Rogue ET201i PRO in MMA mode for MMA welding (electrode holder optional), it is possible to select the Arc-Force percentage and hot start that best suits the welder's operating style; furthermore, from the control panel, it is possible to select the welding mode for electrodes with CELLULOSE coating.

The Rogue ET 201i comes with:

- Instruction manual

This machine replaces the ESAB ROGUE ET200i PRO model and additionally features the PULSE function compared to the previous model.

The Pulse function of the Rogue allows welders to better control heat input and arc stability. The controlled action of the pulse helps create a stable arc, avoiding excessive spatter and minimising the risk of weld defects or the need for post-weld cleaning. The Rogue's Pulse technology facilitates penetration and fusion in the welding process, which is essential for creating strong and durable weld beads and for ensuring the structural integrity of fabricated components. Pulse technology helps minimise the heat-affected zone, thereby reducing the likelihood of material distortion or unforeseen metallurgical changes.
