9-3. Run-In Procedure Using Resistance Grid

Y Stop engine.

Y Do not touch hot exhaust pipe, engine parts, or load bank/grid.

Y Keep exhaust and pipe away from flammables.

1 Resistance Grid

Use grid sized for generator rated output.

Turn Off grid.

2 Welding Generator

Place A/V range switch in maxi- mum position, A/V control in mini-

6mum position, and Output Selector switch (if present) in either DC position.

Weld Cables

 

Connect grid to generator weld

 

 

 

 

 

 

output terminals using proper size

 

 

 

weld cables with correct connec-

 

 

 

tors (polarity is not important).

 

 

 

4

Voltmeter

 

 

 

5 Clamp-On Ammeter

 

 

 

Connect voltmeter and ammeter as

 

 

 

shown, if not provided on generator.

 

 

 

Start engine and run for several

 

 

 

minutes.

 

 

 

Set grid switches and then adjust

 

 

 

generator A/V control so load

 

 

 

equals rated generator output (see

 

 

 

nameplate).

Check generator and meters after

4

 

 

first five minutes then every fifteen

 

 

minutes to be sure generator is

 

 

 

 

 

 

loaded properly.

 

 

 

. Check oil level frequently dur-

+

 

 

 

ing run-in; add oil if needed.

 

 

 

After one hour (minimum), place

 

 

 

A/V control in minimum position,

 

 

 

then shut down grid to remove load.

 

 

 

Run engine several minutes at no

 

 

 

load.

 

 

 

Y Stop engine and let cool.

 

 

 

6

Engine Exhaust Pipe

 

 

 

Repeat procedure if wetstacking is

 

 

 

present.
