11-3. 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 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

 

5

shown, if not provided on generator.

3

Start engine and run for several

 

 

minutes.

Set grid switches and then adjust generator A/V control so load equals rated voltage and current of the generator (see nameplate, rat-

4ing label, or the specifications sec- 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.
