575V 3F TM PFC Multi-link / multivoltage * For optimum flexibility STEL has developed a new and sophisticated PFC Multi-Link which perfects the automatic connection (without any manual operation) of the power source to any input plug in the World from 200V 3 phase to 575V 3 phase. This new technology requires a lower power consumption by the power source which will pull less Amps. * Available only for MAX 403S, Multi-Link 200V 3F
TM PFC Multi-link / energy saving * Power Factor Correction regulating wave form distortion from Input Voltage and Current supply, providing a constant Voltage to the Inverter. In respect of stringent EN Standards for Harmonic Distortion (EN 61000-3-12) and the energy efficiency ERP. Energy savings of 30% compared to a normal Inverter and up to 50% to an SCR. Control of PFC regulation through DSP technology. * Available only for MAX 403S. 30% PFC Energy Saving
infinite reach * The technology of Multi-Link provides suitability for use with extremely long input cables. Potential to access distant working places. At 400V at 1KM with input cable of 4mm. * Available only for MAX 403S. Infinite Reach UP TO 1KM

Unbeatable Technology DFB TEchnology Double Full-Bridge with the use of high performance components and possibility to work with a high frequency of 130KHz, results in a drastic reduction of the Power Source s weight. DSP DSP Digital Signal Processor to have a digital control of the arc to maximize welding performance in all processes. fly back Advance electronic system of auxiliary input voltage (not traditional transformer) which permits control from all power source voltages automatically. stel s igbt module Maximum Flexibility to use any type of component with the added advantage of technology updating.
TM ST Arc (with TOP 504 SM O XM) The MAX 403 with Wire Feeder sytems SM or XM generate greater performance in MIG and MIG pulse. In particular the feature ST Arc allows to automatically compensate any change in the welding conditions owing to workpiece position or operator s hand movements. ST Arc Unlimited Flexibility
ROD-Pulse TM The MAX 403 has the innovative process electrode pulse ROD-Pulse. Normally everybody knows the welding pulse for Tig and Mig, but not for the MMA. STEL has been the first one to develop and present to the market this process with the serie MAX dp 171-201C back in ESSEN 2005 Exhibition. Today this process has been studied in many European Universities with great appreciation. ROD-Pulse The advantages of exterior surface of the weld and arc control are incomparable particularly with cellulosic electrodes. The function ROD-Pulse is available with the remote control RCCS or Feeder TOP 504 SM and XM.
Fig.A Appearance of deposits made with titanic electrode Fig.B Appearance of deposits made with cellulosic electrode ROD-Pulse TM - Better stability of the electric arc (especially at low welding currents); - Possibility to use larger diameter electrodes when welding thin plates; - Reduce the burning through when welding thin plates (low current densities); - A better control of drop transfer through the arc; friendly with the welding operator; - Obtain exterior surfaces of weld with regular scales (finer or coarser depending on the pulse frequency) similar to TIG welding; especially in high frequency welding, 4-5 Hz. IDEAL FOR PIPE WELDING - Assures a better and more sure link in the case of gaps having variable or out of the ax openings (see the orbital welding of large diameter pipes); - Sure penetration and easier to make in the case of one side penetrated butt welding; - Adequate (ideal) in vertical down welding of pipes using cellulosic electrodes;
Power Source MAX 403 mma (electrode) / TIG LIFT - All electrode types including the most difficult cellulosic to weld. - Hot-Start adjustable - Arc Force adjustable - Digital Display Amp/Volt - Tig Lift with slope down adjustable (0-10 sec.) - VRD Safety System - ROD-Pulse (with remote RCCS or Feeders TOP 504 SM and XXM) Robust and reliable to work on the roughest conditions. Easy to carry with weight and dimension reduced
