Microprocessor-controlled, multi-process welding inverter with separate wire feeder suitable for MIG/MAG (manual, synergic, pulsed, double-pulsed and root welding), TIG-DC (continuous and pulsed) and MMA welding. The large 3.3” display shows all the welding parameters, and makes their setting easy and intuitive. In synergic/pulsed MIG/MAG welding, the microprocessor ensures easy and quick setting of the programs thus always guaranteeing optimal arc stability and high welding quality. MIG-MAG features: continuous - pre-set synergic curves – storage of custom welding settings - 2T/4T, spot function selection - pre-post gas time regulation – electronic reactance, soft start, burn back time, hot start, slope down, crater filler. TIG DC features: lift arc - continuous and pulsed welding - 2T/4T - Current, final current up/down slope egulation. MMA features – antisticking - adjustable hot start and arc force. Ideal for professional use, medium-light workshop, metallic furnishings fabrication, industrial and automotive bodyshop, shipbuilding and piping. Thanks to an excellent arc control you can obtain high quality deposition. Possibility to expand the power source with optional function: single pulse, double pulse, root welding. You can also install optional interface to use Spool-gun or Push-pull torch, with analog or digital control. The user can save and recall more then 200 working point and to store them in a customized JOB LIST. Easy to update thanks to USB interface. For models Maxitech 380-500, from the separate wire-feeder the user can set all the parameters up to a distance of 100 meters from the power source.
