Presented by incoil transformers welding transformer with inverter technology model invertec 400 a. Inverter technology adapts primary ac input into dc by full-wave rectifier. Using a high speed electronic switch, the dc voltage is converted to high frequency ac output. The output is filtered and amended to product smooth, low ripple dc welding output. The major helps of inverter technology is to reduce the size and weight of the transformer up to 75% and supply energy saving more than 60% over conventional power supply. This is convenient for welding applications in heavy machinery,trucks or trailers, railcarts, locomotives, tank and pressure vessels, automotive components, metal furniture,structural steel work, sheet metal fabrication, etc. Technical specifications: rating - 7.5 kva; no load current - 0.2 amps; characteristics - constant current/stepless; supply voltage, phaser - 415 [10%, 3-phase 50 or 60 hz; open circuit voltage - 73 v dc; welding current range 5-400 a; maximum i/p current - 12 a; load voltage - 21-35 v dc; weight [approx] - 45 kg; class of insulation - [h] fiberglass; cooling - forced air cooled; and dimension [in mm] - 610 x 360 x 520 [l x w x h].
