Umbilicals

Umbilical control boxes and umbilicals for cutting and welding

New LED Umbilical Control Box

Announcing another innovation by MagnumUSA replacing knife switches for additional safety.

MAGUCB500™

Self-powered LED 500 amp umbilical control box. Patent Pending.

Insert and lock the cables and turn on the DC welder. Watch the box take complete control of the umbilical cables. Turning the switch on makes the umbilical "hot."

Ammeter and voltmeter LED gauges show the true current flowing through the umbilical cables. This is an ideal way of both determining cutting or welding voltage, but also determining umbilical cable resistance over time. The control box is powered from the incoming welding cables so there are no batteries to maintain. Components are designed to handle a range of incoming voltages up to 50 amps from the welder. The master switch controls the solenoid. If the welder goes down, the box automatically shuts down.

Ships with:

Pelican 1300 heavy duty moisture resistant case.
Four female cam locking connectors rated to 500 amp.
Four male cam connectors for incoming and outgoing cables rated to 500 amps.
One DC marine solenoid capable of handling diverse welder inputs.
One master switch controlling current to the solenoid.
One DC LED ammeter self-powered.
One DC LED voltmeter self-powered.
One power light.
One 500 amp shunt.
One 500 amp inline fuse.
All necessary connections.

Reversing the cables on the umbilical side changes the polarity for overhead welding. The control box can easily accommodate lower amperage welders with a simple change of the internal fuse.

Umbilicals

More commercial divers trained on Magnum cutting products than any other brand.

MAG9003

Magnum manufactures umbilical lines from 50' to 100' for use with our 24 volt ignition cans as shown above, or for use with a DC welding machine. Both provide the diver with complete control over voltage for ignition.

Our umbilicals include the following:

R rated .375 diameter 200 psi burst rated oxygen hose.
Ignition cables for positive and negative current.
Switch cables for controlling the solenoid.
Button switch that connects to the ground clamp.
Heavy duty spring operated ground clamp.
Optional striker plate connected to top of ground plate.
Solenoid switch.
Cam lok cable quick connect for torch.
All necessary cables for connecting to batteries or welder.
Shrink wrap straps for cable management.

This item is new to the industry. Divers can now cut underwater with the added security of being in complete control of their ignition, rather than relying on a communication link and a topside tender.

Pressing the button on the ground clamp activates the solenoid. The solenoid closes the negative side of the current going to the torch. When the operator brings the cutting tube into contact with the ground clamp plate, with the button pressed, ignition will take place. If the operator is using our 24 volt system, 24 volts will travel through the torch during ignition. If using a DC welder, 150 amps ignites the torch when the button is pressede and the cutting rod is brought into contact with the ground plate, or the material being ground. As soon as the operator releases the button, the solenoid opens and the circuit is broken.
