Section 2 - Safety Considerations
IMPORTANT
Always turn off the AC power
at the power switch before
servicing or working on the
welder . Failure to turn off the
AC power is an unsafe practice
and can result in injury or death .

AC Power Receptacle
The power cord used on the Dual Servo Spin Welder
has a two–blade, grounding type plug designed for 240
VAC at 20 Amps. It is designed to be plugged into
a 240 VAC, 20 Amp NEMA type 6–20R receptacle as
shown in Figure 2–1. Do not alter the plug or receptacle
in any way.
Grounding
It is important for operator safety that the receptacle
grounding wire be installed properly and securely
attached to an effectively grounded rod. The function of
the ground wire is to keep the Dual Servo Spin Welder
base and housing at earth potential. In the event of a
short circuit from one of the AC lines to the case, the
circuit breaker will open, protecting the equipment and
operator. If there is any question about the grounding
of your AC power, have it checked by a qualified
electrician.
Grounding lugs are also provided, one on the back of the
base (see Figure 2-2) and one on the back of the welder
housing. You should connect a separate 14 AWG*
ground wire between these lugs and an effectively
grounded metal pipe. This will minimize any external
electrical interference from leaking into the Dual Servo
Spin Welder control circuitry. This will not compromise
the safety of the power ground.
* 14 AWG wire has a diameter of 1.63mm or 0.064”
Mechanical Safety
The Dual Servo Spin Welder is capable of developing
substantial torque, force, and high rotational velocity.
Keep your hands and body away from the tool head
during operation. The spinning head is capable of
inflicting serious injury. Never attempt to retrieve a part
from a spinning tool head. Always wear a face shield
when operating the spin welder. Be extremely careful not
to let long sleeves, ties, necklaces or long hair become
entangled in the welder during operation. Always
turn machine power off when installing or removing
tooling.
