The MIG 175 portable wire feed welder case contains all the components of the welder.
The right side has the wire feed assembly, spool hub, gun trigger connections and polarity connections.
The left side houses the electrical components: transformer, reactor, current capacitor, cooling fan, controlling
transformer, PCB, heat radiator and the rectifier bridge.
The front panel contains the voltage and wire feed speed (amperage) control knobs, on/off switch, opening for the
gun connection, cooling openings, ground cable and gun trigger connections.
The back panel consists of the power cord, cooling opening and gas valve connection interface. (See the Chart
