10-2. Run-In Procedure Using Load Bank

!

!

Stop engine.

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

4

 

!

Keep exhaust and pipe away

 

 

 

from flammables.

2

 

NOTICE − Do not perform run-in

 

 

procedure at less than 20 volts weld

 

1

output and do not exceed duty

 

cycle or equipment damage may

 

 

 

 

occur.

 

 

1

Load Bank

 

 

Turn all load bank switches Off. If

 

 

needed, connect load bank to 115

 

 

volts ac wall receptacle or genera-

 

 

tor auxiliary power receptacle.

 

 

2

Welding Generator

 

 

Place A/V range switch in maxi-

 

 

mum position, A/V control in mini-

 

 

mum position, and Output Selector

 

 

switch (if present) in either DC

 

 

position.

 

 

3

Weld Cables

 

 

Connect load bank to generator

 

 

weld output terminals using proper

 

 

size weld cables with correct

 

 

connectors. Observe correct

 

 

polarity.

 

 

Start engine and run for several

3

 

minutes.

 

Set load bank switches and then

 

 

 

 

adjust generator A/V control so

 

 

load equals rated voltage and

 

 

current of generator (see name-

 

 

plate, rating label, or the specifi-

 

 

cations section in this manual).

 

 

Check generator and load bank

 

 

meters after first five minutes then

 

 

every fifteen minutes to be sure

 

 

generator is loaded properly.

 

 

NOTICE − Check oil level frequent-

 

 

ly during run-in; add oil if needed.

It is recommended to run the weld- ing generator for two hours mini- mum and up to four hours under load. Place A/V control in minimum position, then turn off load bank to remove load. Run engine several minutes at no load.

! Stop engine and let cool.

4 Engine Exhaust Pipe

Repeat procedure if wetstacking is present.
