10-3. Run-In Procedure Using Resistance Grid

 

 

Y Stop engine.

 

 

Y Do not touch hot exhaust

 

 

 

pipe, engine parts, or load

 

 

 

bank/grid.

6

 

Y Keep exhaust and pipe away

 

 

from flammables.

 

 

 

 

2

Y Do not perform run-in

 

 

procedure at less than 20

 

 

 

volts weld output and do not

 

 

 

exceed duty cycle or equip-

 

 

 

ment damage may occur.

 

 

1

Resistance Grid

 

 

Use grid sized for generator rated

 

 

output.

 

1

Turn Off grid.

 

 

2

Welding Generator

 

 

Place V/A control in minimum posi-

 

 

tion, and Output Selector switch (if

 

 

present) in either DC position.

 

 

3

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

3

5

minutes.

Set grid switches and then adjust

 

 

 

 

generator A/V control so load

 

 

equals rated voltage and current of

 

 

the generator (see nameplate, rat-

 

 

ing label, or the specifications sec-

4

 

tion in this manual).

 

Check generator and 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 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.
