preheat output, then turn on ignitor output, after ignition, turn off ignitor output, keep gas and low preheat
output, preheat starts, after preheat, pierce starts.
Don’t use auto ignitor
1, when ignite, ignition time set 0, firstly press K1 to open gas and low preheat output, manually ignite gas
2, when pierce, controller doesn’t open ignitor output, ignition time skip, directly preheat starts
Pierce Time: after preheat, torch moves up to pierce position, open cutting oxygen (high oxygen) output, the
time of pierce starts
Move Pierce Time: after start pierce, before torch moving down to cutting height, X and Y start moving time,
the time is to avoid steel slag
Torch Up Time: after cut, torch move up time
Torch Down Time: after ignition, torch move down time
Note: 1, torch up time and torch down time decide torch idle-run and preheat height, usually up time is longer
than down time
2, before start cutting every time, firstly move torch to align plate start point, and adjust torch to proper
cutting height, then start, controller firstly executes torch up, then idle-run to pierce position and ignite, after
ignition, move down to cutting height (torch down time), after cutting, execute torch up, idle-run to start
position, don’t execute torch down, so before next start, firstly need to adjust torch to proper cutting height.
Pierce up time: after preheat, torch move up time
Pierce down time: after pierce, torch down time
Note: 1, pierce up time and pierce down time decide torch cutting height, usually up time is longer than down
time.
2, move up before pierce to avoid steel slag
Cut Close Time: after cutting, keep cutting output time, to avoid lag angle, after the time, torch starts to move
up
Ignitor: when set 0, before move to the next pierce point, keep gas and low preheat output (with fire), set 1,
close gas and low preheat output after cutting current part, ignite again at the next pierce point
High Preheat Oxygen: when set 0, don’t use high preheat, when set 1, use high preheat to assist preheat
Low Preheat: 0 to close low preheat during cutting, 1 to keep low preheat during cutting
High Preheat: 0 to close high preheat during cutting, 1 to keep high preheat during cutting
Note: can’t set 0 at the same time of keep low preheat and keep high preheat
