1.16 Loading a program
The controller has a factory preset read-only “mem0” program, which contains
operational parameters of the carriage and oscillator.
To load a previously saved program, „memX” string must be shown on the
display, where X is the number of a recently used program.
Switch the main switch on control box off and on again.
Rotate the travel speed button (B), to select a required program number.
To load the parameters and apply the choice, press the button (B).
1.17 Operation
The carriage can operate with or without the oscillator. To operate without the
oscillator, dismount it according to instructions from point “Design of the carriage
without oscillator”. Plug the power cord of the control box into the power supply
and turn on the power by toggling the power switch to upper position. Then the
controller will automatically check for the oscillator connected to the oscillation
socket, which will be confirmed on the display.
Position the torch at the starting point of the welding and set required process
parameters or load them from a saved program. If the travel direction switch A is
set to middle position, toggling the lever to position TEST will enable the arc for
a while (toggle the lever to ‘I’ to enable constant welding).
Then, set a direction of travel using the travel direction switch A, which will start
movement of the carriage with the programmed parameters. If the arc ignition
switch L is set to position ‘0’, the carriage will move according to the programmed
parameters but without welding. At this moment the display will show the current
travel speed of the carriage. All parameters can be readjusted during operation.
The carriage will stop after reaching a limit switch (if the switch J is set in upper
position; the oscillator will also stop) or when you toggle the travel direction
switch A to middle position. If the switch J is set in lower position, then after
reaching the limit switch the oscillation will stop and the carriage will start
travelling in the opposite direction. In such case you can quickly increase the
travel speed to maximum by pressing and holding the travel speed adjustment
knob B for 2 seconds.
If an error occurs, the display will show “ErrX” message, where X is the number
of the error.
Once the operation is finished, turn off the power and unplug the carriage from
the power supply.
