13-3. Run-In Procedure Using Resistance Grid

Stop engine.

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

6

Keep exhaust and pipe away

from flammables.

 

NOTICE − Do not perform run-

2in procedure at less than 20 volts weld output and do not exceed duty cycle or equip- ment damage may occur.

Resistance Grid

 

 

 

Use grid sized for generator rated

 

 

1

output.

 

 

Turn Off grid.

 

 

 

 

 

 

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 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

3

5

 

shown, if not provided on generator.

 

Start engine and run for several

 

 

 

 

 

 

minutes.

 

 

 

Set grid switches and then ad-

 

 

 

just generator A/V control so

 

 

 

load equals rated voltage and

4

 

 

current of the generator (see

 

 

nameplate, rating label, or the

 

 

 

 

 

 

specifications section in this

 

 

 

manual).

+

 

 

Check generator and 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 shut down grid to

 

 

 

remove load. Run engine several

 

 

 

minutes at no load.

 

 

 

 

Stop engine and let cool.

Engine Exhaust Pipe

Repeat procedure if wetstacking is present.
