Unlike other ,(YD Lincoln uses micro processor con-
trol to monitor and establish the arc without the stick-
ing and shorting of the electrode to the job as seen in
many other ,( installations. Due to the requirement
of the resistance in the circuit to be low, for a ,( to
operate, a good metal-to-metal contact must be made
between the metal core of the electrode and the job.
Any damaged connection anywhere in the output cir-
cuit may limit the operation of the ,(. This includes
a good connection of the work return clamp and the
job. The work return clamp should be connected close
as practical to where the welding will be performed.
Some electrodes form a cone at the end of the elec-
trode after the welding arc has been broken, particu-
larly iron powder and low hydrogen electrodes.
This cone will need to be broken off in order to have
the metal core of the electrode to make contact.

The starting technique that has successfully overcome
the problem is the push, twist, and peel technique.
This technique requires the operator to push the elec-
trode into the joint and twist.
The Push and Twist breaks off the cone and allows
the metal electrode to make contact.
The peel and lift of the electrode establishes a con-
trolled start to the welding arc. Normal welding tech-
nique for the application is then used.

The engine used to supply power for your welder is a
heavy duty, industrial engine. It is designed and built
for rugged use. It is very normal for any engine to use
small quantities of oil until the break-in is accom-
plished. Check the oil level twice a day during the
break-in period. In general this takes 50 to 100 hours
of operation.
