Introduction The SifWeld MTS200 is an inverter welder which adopts the latest Insulated Gate Bipolar Transistor (IGBT) technology. The working principle is to use a single tube IGBT switching device rectifying input power into a DC output then inverted to a high frequency, then stepped-down through the pulse width modulator (PWM) to produce the welding output.
Technical Data Model SifWeld MTS200 Item Power Voltage (V) 1ph AC 230/240V Frequency (Hz) 50/60 Rated Input Current (A) I-1max 40.6 Rated Input Current (A) I-1eff 20.3 5-200 Rated Current 5-200 Range 30-200 Recommended Fuse Rating No Load Voltage 20.2-28...
Installation The SifWeld MTS200 is equipped with a network voltage compensation device, this ensures that when the network voltage changes within the 15% range, the machine can still continue to work. The cross-sectional area of any extension cable must be above the cross-sectional area of the machines mains input cable to minimise voltage drop.
