Closed-loop control All arc welding processes Controls 4 parameters 25 program memory Synergic TIG control Multi-pass capability > Introduction Integrated welding systems rarely consist of just a welding power supply. Consequently, control of the welding sequence is only partially addressed using the type of sequence control normally available with welding power supplies. Even though some of these controllers are of a microprocessor design, they can only control the output of the welding power supply and are often limited to a specifi c weld process. An integrated welding system, in ad- dition to controlling welding current, requires control of other parameters such as wire and travel speed and, in some cases, control of arc length through the control of arc voltage. Firmware The 9500 Controller is of a microprocessor design, similar to a computer. In addition to the "hardware" which is the control itself, the operation of the unit is based upon "software". The operation of the 9500 Controller is controlled by a software program in the same way as a computer. The main difference is that the software is permanently loaded on two EPROM memory chips. The program is burned into the chip and cannot be changed by the user. The program and the chip are together known as "fi rmware".To make the 9500 System Controller suitable for a number of different welding operations, Jetline has developed a series of fi rmware options. EPROMS, loaded with all the appropriate fi rmware, will be installed in the controller at the time of supply. If, however, it is required to add options or change the weld process at a later date, new EPROMS containing the new fi rmware can be supplied to retrofi t the controller. Description The 9500 System Controller is a microprocessor based unit designed and built to provide economical, ac- curate control over the complete welding process. The unit will control all arc welding processes and, although primarily designed for systems utilizing Jetline equipment, can easily be used with other manufacturer's equipment and on other welding systems.The control is compact and is capable of controlling up to four welding parameters using appropriate control modules which are individually available as optional equipment. The output level of each parameter is set using an integrated digital keypad and is displayed on a fl uorescent display. The 9500 Controller includes sequence start and stop buttons as well as an emergency stop button. An important advantage of the 9500 Controller, compared with more conventional units, is that it employs a menu system to create weld programs through the keypad. Actual values can be entered and are displayed. This permits the parameter levels to be pre-selected before welding starts. During welding, the display provides a readout of actual weld values. 15 Goodyear St, Irvine, California, 92618 U.S.A. Tel: (949) 951-1515 Օ Fax: (949) 951-9237 size="-2">

The 9500 Controller produces analog output volt-ages which can be connected to most types of solid-state controlled equipment. The standard model is ideal for GTAW, both DC and AC currents and, with optional fi rmware, can be used to control plasma, GMAW or SAW systems. > The 9500 Controller can be used for many differ- ent applications. The standard model is complete with fi rmware for the control of the GTAW process. It includes all the features necessary for the control of a GTAW seam welder and controls the weld- ing power supply, arc length control, cold wire feeder and travel...

The unit has the ability to store programs (or weld schedules). The system is designed to store 25 programs, easily identifi able by part number. Any schedule can be easily called up by the operator for welding. During programming of the weld schedule, any existing program can be copied. After copying, any required changes can be made. This provides a quick and easy way of reproducing schedules for various materials or thicknesses. sequence. The system can be set to move the part after the arc is extinguished to allow the start of the second pass to be separated from the end of the fi rst....

(Optional): Stores 25 multi-pass schedulesInput: 120/240V 1 phase, 50/60Hz > This option permits the diameter of the part be-ing welded to be recorded in the weld program. When programming, the travel speed can then be entered as a direct surface speed in in/min or cm/min. During welding, the indicated speed will also be the surface speed.
