A.5 Main Settings
Clicking the “Setup” button will open the Setup Main screen under the iHC Info Bar.
This screen
• Continuously displays the actual Arc Voltage and the height of the torch from the plate (the height where the plate was sensed at the time
of pierce).
• Has various tabs for more functions.
Most of the parameters of the iHC can be directed in the Setup window. The upper and rightmost part of the Setup-window consist of buttons
and fields which are always displayed. The lower left part of the Setup consists of several tabs.
This screen is used for intuitive setting of iHC operation parameters. When setting any of these parameters the process diagram visually indicates
what each parameter means.
• Slow Down Height is the distance from the last known plate height where the lifter should slow down the motion for plate sensing to avoid
a hard hit.
• Ignition Height determines the distance from the plate where the torch will be ignited.
• Pierce Height determines the distance from the plate where the actual piercing will be done after igniting the torch.
• Pierce Height Time determines how long the torch will stay on pierce height.
• Pierce Down Speed determines the transfer speed from pierce height to cut height.
• Cut Height determines the torch height for cutting after piercing is complete.
• Cut Height AVC Delay determines the time given for the arc voltage to stabilize after reaching the cut height to allow for control of the
torch height based on measured Arc Voltage (also proper cutting speed is required).
• Hold ON Cutting voltage increase required to freeze torch motion while crossing kerf
• Hold OFF Cutting voltage increase below while torch motion recovers to AVC control
• Transfer Height determines the height where the torch will be lifted after the cut for rapid transfer to the next pierce point. Use high enough
value to avoid collisions.
• Transfer Height Timeout determines how long the system waits at this height for the new pierce command before lifting the torch all the
way up to home position.
• Arc Voltage Display shows actual arc voltage in real time when cutting is active.
• Plate Position shows where the plate was last sensed in comparison to the Torch Lifter Home position.
