The microprocessor based Modular Weld Controller is the main control module and provides all control and communication functions and can program external motion control axis via the Local Area Network (LAN) port.

The controller can support up to four stepper motor controlled axis, using the MSC-2 Micro-step Controller, and four DC servo controls, using the DMC-2 DC Servo Controller.

The MWC-1000 provides all external Input / Output control interface and electrical connections to user supplied components.

The MWC-1000 consists of two major control systems. The first is a Programmable Logic Controller (PLC) and the second is the Modular Weld Control (MWC). The PLC is the main controlling element and provides the interface between the MWC and the external I/O functions. The PLC is configured by using the terminal serial port. The user can define up to 150 sequences that will be executed by the specified switch inputs. The MWC control provides all of the weld control functions and can be programmed for up to 40 weld schedules via the terminal serial port or remote pendant port.


	User definable configuration

	RS-232 Serial Port

	Flexibility to adapt to most solid state equipment

	Ease of set-up


	40 Weld Schedules and 150 PLC Sequences are user programmable

	Permits off-line programming, system configuration and remote control

	Permits user to employ existing equipment in many cases

	Welding Parameters displayed while welding using optional remote pendant

	Automatically recognizes installed peripheral devices


	Prepurge Gas Flow Time
	Arc Start Parameter Time
	Arc Active Delay Time
	Ramp Up Time
	Weld Time (spot or manual)
	Ramp Down Time
	Crater Fill Time
	Wire Retract Time
	Burn Back Time
	Post Purge Time
	Pulse On Time*

	S1 = Cycle Start			S6 - S7 = Ramp Down
	S1 - S2 = Prepurge Gas Flow Time			S7 - S8 = Crater Fill Parameter Time
	S2 - S3 = Arc Start Parameter Time			S8 - S9 = Wire Retract Time
	S3 - S4 = Arc Active Delay Time			S9 - S10 = Burn Back Time
	S4 - S5 = Ramp Time			S10 - S11 = Post Purge Time
	S5 - S6 = Weld Time (spot or manual)

The optional WELDSEQ Plus Software is designed to operate in conjunction with our MWC weld sequence controllers. The program provides a serial communications program, which is used to communicate with the MWC and program the Programmable Logic Controller (PLC) and configuration parameters.

The program provides a full function, user configurable ASCII terminal program, which can be used to configure all of the WSC/MWC functions. It provides weld data collection routines that allow the user to collect run-time weld data and store this data for future analysis.

The MWC weld schedules can be edited and include a Weld Setup specification sheet, which is used to save process specific information for the current weld schedule. The program also provides a PLC editor, which can be used to generate custom PLC programs.
