2-Level Detection System
The simpler design is available with the MedWeld 3005 control. This design
incorporates the use an independent safety monitoring system to supervise the
integrity of the ground cable and monitors for primary current imbalance. If a fault is
detected, the safety system will isolate the welding gun from the power lines by
tripping the circuit breaker. An under-voltage trip breaker is used for failsafe
condition.
The power to sustain the breaker operation must come from an external source or
from the line side of the circuit breaker. When taking power from the line side of the
breaker, the use of special “Touchsafe” fuse holders is required.
2-Level Manual Gun Safety Protection System Option Installed
For use with the MedWeld 3005 Series Controls
This includes a GFI monitor and a current imbalance-monitoring coil with push to test
button & indicator.
“Touchsafe” Switch & Power Supply Installed
This option is required for use with the manual gun safety system for under-voltage
trip breaker if external power is not provided. The power is taken from the line side
of the circuit breaker and can be disconnected safely. The power supply is to
energize the GFI Monitor System and the UV mechanism of the circuit breaker.
