The CSC > TM MIG Weld Process Controller (controlledshort circuit) was developed to virtually eliminate welding spatter and increase welding travel speeds on thin materials. The process is capable of produc- ing cold wire feed GTAW (TIG) quality welds at GMAW (MIG) welding travel speeds. The system incorpo- rates the following features:Microprocessor controlՕHigh speed, high precision stepper motors Direct drive wire feeding system ՕIntegrated wire feed head and GMAW torch Palm > The CSC > TM control coordinates the feeding directionand speed of the electrode with the level of welding amperage delivered by the power supply. The process has two primary phases - arc phase and short circuit phase. The control monitors the voltage between the electrode and the work to determine which phase the process is in at any given time. If the voltage is above the "Voltage Hi" threshold setting, the process is in the arc phase. If the voltage is below the "Voltage Lo" threshold setting, the process is in the short circuit phase.The control adjusts the level of current being deliv-ered from the welding power supply based on the phase of the process. Each phase, arc and short, are divided into three segments - start, pulse and final. These three current segments for each phase are used to control the bead shape and size based on the application.The arc phase is the phase during which heat isgenerated to melt the base metal and the filler material. The molten droplet is deposited in the short phase when the wire makes contact with the weld puddle. During the short circuit created by the droplet of filler material, the voltage drops below the voltage "Lo" threshold and the controller starts to retract the wire to clear the short.The controller senses the short has cleared when theprocess voltage rises above the Voltage Hi thresh- old, and the wire is retracted to the preset arc length level.Once the arc is again established, the control beginsfeeding the electrode toward the welding puddle and the cycle repeats. > TM User InterfaceՕSimple user interface with lockout capabilities DC welding process ՕCompatible with mild steel, stainless steel, alumi-num, silicon bronze and othersProduces excellent results on material thick-nesses ranging from 24 ga. to 12 ga.ՕWire range from 0.035" to 0.093" (0.9 mm to2.4 mm)Virtually spatter free GMAWՕReduces fumes and heat input The 0.025" (0.6 mm) thick 304 stainless steel materialwas welded with 1/16" (1.6 mm) wire on a Jetline seam welder using the CSC > TM MIG process at atravel speed of 100 ipm (254 cm/min). >

The controller allows the opera-tor to adjust the welding wire feed speed, the average am- perage, and the arc length. These parameters are sufficient for most applications.However, in high travel speedinstances and custom applica- tions, additional adjustments may be required. These adjust- ments are made using thePalm > TM interface. The Palm > TM User Interface allows the operator to connect anM Series Palm > TM directly to the CSC > TM control usingthe Palm > TM Serial Hotsync cable.
