Product Description

The Magnum SG Control Module is an interface between the welding power source and the Magnum Spool Gun. The Control Module and Spool Gun combination provide a system for welding primarily with aluminum electrode wire using a con- stant voltage welding power source.

The Control Module provides control of both wire speed and gas flow. It also provides connections from the welding power cable, control cable, and gas hose from the power source and gas cylinder regulator to the spool gun.

The Control Module will operate with any power source that provides constant voltage welding output and has an output contactor.

Power Source

The Control Module will operate with any Lincoln CV or CV/CC power sources, with many Lincoln engine-driven welders (see the complete list at the end of this section), and with many non-Lincoln type power sources.

In general, power sources must have the following:

1.A constant voltage (CV) type welding output.

2.Capability to supply 115 volt AC power to the control module.

3.Optional for “cold electrode” switched welding output: An output contactor. It can be either of two types:

A.Switch closure: Internally-energized type actuated by an external switch.

B.115 VAC: Externally-energized type actuated by

115 volts AC supplied from the control module to the power source.

A selector switch on the back of the control module is used to select which of these two types of control circuit is being used. It is imperative that this switch be set correctly before attaching to the power source. See “Setting the Mode Switch on Rear Panel” for more details.

Optional Accessories

Several accessories are optionally available for use with the

K488 control module, and they are as follows:

1.Three 10 ft. (3.0m) input cable assemblies are available and consist of control and electrode cables and gas line. The proper input cable assembly must be ordered in addi- tion to the control module; as none are included with the control module:

A.K492-10 for use with Lincoln CV power sources having terminal strip control connections (Lincoln R3S, CV-400, and DC family machines). Can also be used with non-Lincoln CV power sources.

B.K493-10 for use with Lincoln CV power sources having 14-pin control cable connection (Lincoln CV and CV-I series, Invertec V-200).

C.K691-10 for use with Lincoln engine-driven power sources having 14-pin control cable connection and/or 115VAC outlet.

2.K473 Spool Gun Extension Cable. 25’ extension cable extends distance between spool gun and K488 control module.

3.K518 Adapter for K469 Spool Gun. Adapts K469 spool gun to K488 Control Module or to K473 Extension Cable.

The control module is not required when connecting Magnum spool guns to Lincoln models SP-150 or SP-200, which have built-in wire feed control circuits. In addition, the Lincoln models SP-250, SP-255, Wire-Matic 250, Wire-Matic 255 do not require the control module when the optional K607-1 or K672-1 Spool Gun Adapter kit is installed, since these kits also provide wire feed control circuits.
