• WELD SEQUENCE AND LEVELS – A weld schedule is started by manually initiating
Sequence Start. Once the sequence is started, the system operation of functions is fully
automatic.
A weld schedule has the ability to change values for most functions as the electrode
traverses around the tube. The weld schedule is broken down into LEVELS and each level
can contain a change to one or more functions. A weld schedule can contain up to 100
levels. The advance from level to level is automatic and can be programmed by time or
degrees.
• TRAVEL FUNCTION –
The system is equipped with a motor servo controller that
provides the power and regulation for rotating the electrode around weld seam. The
rotation is programmed in revolutions per minute (RPM) and can be programmed to
rotate continuously or stepped (synchronized with current pulsation).
• PULSATION –
The system can rapidly change or pulse back and forth between two
different values of current and two different values of rotation travel. The HIGH value is
designated as the PRIMARY value and the LOW value is designated as the
BACKGROUND value. The pulsation rate is programmed by setting both the PRIMARY
and BACKGROUND PULSE timers.
• FAULT STATUS –
The system monitors arc gas flow, arc volts and power supply
temperature. If any of these functions fall outside certain limits the system will alert the
operator and weld schedule will be halted (See Section 5.3).
• GAS FUNCTIONS –
As stated, the Model 205 is intended for the GTAW process. This
process requires a welding gas (usually inert) for operation. The Model 205 is equipped
with a gas solenoid and input/output connectors for the control of the welding gas. Flow
rates are not controlled by the power supply and must be set via an external flow meter.
• PRINT FUNCTIONS –
A thermal printer is built into the Model 205. It will print the library
of weld schedules as well as the programmed values and associated data of a specific
weld schedule.
• WELD DATA RECORDING – The system has the capability of recording data from the
weld. This data is feedback data from both the Travel and Current servos and is
recorded every 0.1 second. This data is saved to the hard drive of the Model 205 as a
Weld Data Record. The name of the Weld Data Record is a concatenation of the Power
Supply & Power Supply Serial Number & Weld Schedule Name & Weld ID. This record
can be exported to a USB memory stick to be loaded to a PC then viewed / printed.
Note
A Weld Data Record can ONLY be created in Weld Mode and ONLY when Weld Data
Recording is enabled.
