SECTION 10 − RUN-IN PROCEDURE

run_in3 8/01

10-1. Wetstacking

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

Welding Generator

 

 

Run diesel engines near rated volt-

 

2

age and current during run-in period

 

to properly seat piston rings and

 

 

 

 

prevent wetstacking. See name-

 

 

plate, rating label, or specifications

 

 

section in this manual to find rated

 

 

voltage and current.

 

 

. Do not idle engine longer than

 

 

 

necessary. Piston rings seat

 

 

 

faster if engine runs at weld/

 

 

 

power rpm, and the welding

 

 

 

generator is kept loaded during

 

 

 

run-in.

2

Engine Exhaust Pipe

 

 

Wetstacking is unburned fuel and

 

 

oil in the exhaust pipe and occurs

 

 

during run-in if the engine is run too

 

 

long at light load or idle rpm.

 

 

If exhaust pipe is coated with a wet,

 

 

black, tar-like substance, dry the

 

 

engine using one of the following

 

 

run-in procedures.

 

 

See the engine manual for addition-

 

 

al engine run-in information.
