Description: DIGITALLY PROGRAMMED, SYNERGIC MG-400 TP and MG-500 TP welding machines are new generation thyrister controlled CO2/MAG welding machines with a one-knob integrated micro-processor synergic control, which provides appropriate voltage for the welding current selected. This allows an inexperienced operator to handle the machine without wastage or re-work. The machine delivers a built-in preset voltage programme to accommodate the amperage (wire-feed speed). Separate control mode for amperage and voltage is also provided as standard feature. Easy-to-read and precise current voltage scale indicates adjusted value due to the effect of the gas mixture and wire diameter. The user-friendly and technologically advanced Penetration Control keeps the depth of penetration at a constant level, even when the tip-to-work distance varies. This assures a high quality of welding. Microprocessor controlled instantaneous arc start close to 100% from low to high current, allows instantaneous arc start even at low current, virtually every time. The combination of hot start and wire slow-down start control delivers secured arc start. These synergic digitally programmed MIG welding machines are offered by Arc-Tec.
