Section 2 - Safety Considerations

Electrical Safety

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.

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..
