GAW-135H — GENERAL INFORMATION

GAW-135H Familarization

General Inspection Prior to Operation

This generator/welder has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have become disloged in transit.

The MQ Model GAW-135H generator/welder has been designed as a portable lightweight power source for 60 Hz (single-phase) vibrators, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

This generator/welder is powered by a Honda GX200VEN2,

5.5HP, air-cooled gasoline engine. The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

The generator is mounted on rubber vibration isolators that have a steel base backplate which is attached to the protective steel pipe carrying frame.The protective carrying frame is made of steel tubing and fully wraps around the generator to protect against damage.

This portable generator is supplied with a electrical control panel. The control panel includes items as listed below.

Control Panel

The generator control panel has the following componets:

z(1) NEMA Duplex Receptacle (GFCI) 5-20R (120V,

20 Amp)

zOne main 2-pole,15 Amp Circuit Breaker.

zIdle Control Switch

zWelding Terminal Lugs

zGround Terminal

Circuit Breaker

To protect the generator from an overload, a 2-pole, 15 amp circuit breaker is provided on the control panel. Make sure to switch this circuit breaker to the "OFF" position prior to starting the engine.

Excitation System

The MQ generator/welder uses a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnet passes the coil it produces approximately 19-22 AC volts.

This voltage (19-22 VAC) is then sent to the control box that contains three rectifying diodes:

zExcitation (diode 1)

zBattery (diode 2)

zSlow Down (diode 3)

The AC voltage will pass through the excitation diode that converts the voltage to DC power.

This DC power is then sent to the excitation windings housed within the main windings commonly called the "stator".

This voltage is then transferred into the rotor through induction.The rotor contains two diodes within it which rectify the DC voltage and send it out through the main windings, as AC voltage.

Engine

The four-cycle air-cooled Honda gasoline engine is designed to meet every performance requirement of this generator. Reference Table 1, for engine specifications.

Figure 2 shows the basic controls and indicators for the MQ GAW-135H generator/welder.
