The PROTIG 230 AC/DC FV is a compact, portable and versatile dual-process unit for AC/DC TIG welding and coated-electrode (MMA) welding. It can be used to join all types of material up to 4 mm thick (steel, stainless steel, aluminium, copper, magnesium and even titanium). PFC technology ensures that it can operate from 195 V to 265 V, and still produces a very stable arc, even if a 100m extension lead is being used. Standard DC: direct current welding for most ferrous materials. Pulsed DC: limits the temperature rise of the parts being welded. Ideal for very thin sheet metal. Standard AC: for welding aluminium and its alloys (Al, AlSi, AlMg and AlMn, etc.). Pulsed AC: limits the temperature rise of the parts being welded. Ideal for very thin sheet metal. Easy AC: predefined user settings makes using the welding unit as simple as possible. The user only has to select the tungsten-electrode diameter on the machine’s user interface. SPOT mode (AC or DC TIG): for fast and accurate spot welding before working on thin sheet metal. Two ignition types: HF contactless or HF contact for electrosensitive environments. Three types of trigger control: 2T, 4T and 4T LOG. Automatic torch detection: compatible with trigger and double-button torches. MMA : basic and rutile electrodes (up to Ø 4 mm). Pulsed MMA: enables vertical-up welding (for pipes and pipelines, etc.). Three built-in welding aids: - Anti-Stick: minimises the chance of the electrode sticking to the workpiece. - Adjustable Hot Start: makes ignition much easier and can be adjusted in seconds depending on the type of metal. - Arc Force: a one-off current boost for resolving difficult welding situations. Stores up to 30 programs per welding process. Access to an advanced menu for maximum welding control. Current and voltage display both during and after the welding process (DMOS/QMOS). Reinforced bodywork and anti-shock pads. Space-saving and easy to move around the site. Its smart ventilation system reduces power consumption, dust intake and noise levels. Surge-protected up to 400 V (PROTEC 400).
