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 nameplate, rating

 

 

label, or the specifications 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.

 

 

. Check oil level frequently dur-

 

 

 

ing run-in; add oil if needed.

 

 

After one hour (minimum) place A/V

 

 

control in minimum position, then

 

 

turn off load bank to remove load.

 

 

Run engine several minutes at no

 

 

load.

 

 

 

 

Y Stop engine and let cool.

Engine Exhaust Pipe

 

 

 

Repeat procedure if wetstacking is

 

 

present.
