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 ad- just generator A/V control so load equals rated voltage and current of the generator (see

4nameplate, 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.

. Check oil level frequently dur- ing 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.

Y Stop engine and let cool.

6 Engine Exhaust Pipe

Repeat procedure if wetstacking is present.
