When, the end of welding wire 136 is retracted automatically in the end of ignition tip 144.In another embodiment (not shown), and before
Discussion it is consistent, ignition tip can be longer or shorter than the content of illustrated explanation in Fig. 6 a- Fig. 6 c.
Fig. 7 is the flow for an embodiment for illustrating the automatic silk retracting method 700 for welding equipment 100
Figure.As shown in Figure 7, it is configured to be powered in 702 welding equipments.704, have the computer of automatic silk retraction program true
Determine whether user attempts to enter setting menu by user interface or computer.If just sought entry into 704 users
Menu is set, then determines to set whether menu is locked in optional 706 computer.If menu quilt is set optional 706
Locking, then determine whether user inputs correct password in 708 computers.If set, menu is locked and user does not have
There is the correct password of input, then prevent access arrange parameter in 710 computers and return to previous user interface option
To user.If set, menu is locked and user have input correct password really, allows to make in 712 computers
User's access sets the parameters to enable or disable automatic silk retraction program.User enable or disable automatic silk retraction program and
After any relevant parameter, previous user interface option is returned into user in 714 computers.For example, user
Can adjust it is at least one in parameters described below, including：Retract time delay, retract the time, retract distance and close to sensing
Device parameter.
If being not intended to enter in 704 users and setting menu, determine whether welding gun trigger is opened in 716 computers
With.If welding gun trigger is not activated and welding equipment has electric power, in the waiting of 718 computers until welding gun triggers
Device is activated or user seeks entry into setting menu.If be activated in 716 welding gun triggers, in 720 feeders
Start and the source of welding current supplies electric power.722, computer determines whether welding gun trigger is disabled.If welding gun trigger
Do not have it is disabled, then in 724 computer monitoring welding gun triggers.When disabled in 722 welding gun triggers, in 726 computers
Determine whether welding arc is off.If be not off in 726 welding arcs, in 728 computer monitoring welding arcs.
When being off in 726 welding arcs, computer tracking waiting time delay, and determine waiting time 730
Whether delay is more than the retraction time delay set in user interface.For example, time delay of retracting can be more than zero
Any time.If waiting time delay is less than the retraction time delay set in user interface, computer continues to monitor
Waiting time postpones.If waiting time delay is at least equal to the retraction time delay set in user interface, in 732 meters
Calculation machine checks whether welding gun trigger is activated.If be activated in 732 welding gun triggers, start simultaneously in 720 feeders
And source of welding current supply electric power.If it is not activated in 732 welding gun triggers and waiting time delay is at least equal to making
The retraction time delay set in user interface, then be based on user interface parameter retraction welding wire in 734 automatic silk retraction programs.
For example, welding wire can retract up to a time quantum or distance to a declared goal.736, computer determines whether welding gun trigger is activated.
If be activated in 736 welding gun triggers, start in 720 feeders and the source of welding current supplies electric power.If in 736 welderings
Rifle trigger is not activated, then returns to the method incipient stage at 704 in 738 computers.It is important to note that, prolongs in retraction
Activation trigger device is possible during the slow time, this can restart welding operation, as welding gun trigger is used 732.In weight
Waiting is fully retracted delay period and is not necessarily to before opening welding.
In the another embodiment of the method, computer is for the biography on overcurrent or torque monitoring silk feeder
Dynamic case drive motor, wherein overcurrent or torque can indicate the problem of related to automatic silk retracting method.In any situation
Under, it has to be understood that, it can be so configured using the welding equipment 100 of automatic silk retracting method 700, so that working as welder
When stopping welding up to specified time amount, welding wire is at least retracted in the end 140a or ignition tip 144 of nozzle 140.
In the another embodiment (not shown) again for the automatic silk retracting method 700 of welding equipment 100, method
700 including at least one in following methods step.If welding gun trigger is activated, silk feeder starts and welds electricity
Electric power is supplied in source.Whether computer is configured to determine welding gun trigger disabled.If welding gun trigger do not have it is disabled,
Computer monitoring welding gun trigger.Alternatively, when welding gun trigger is disabled, computer determines whether welding arc is put out
Go out.If welding arc is not off, computer monitoring welding arc.Once welding arc is off, then computer quilt
Configure to follow the trail of waiting time delay and determine whether waiting time delay is more than the retraction set in user interface delay
Time.If waiting time delay is less than the retraction time delay set in user interface, when computer continues to waiting
Between postpone to be counted.If waiting time postponed at least equal to the retraction time delay set in user interface, calculate
Machine checks whether welding gun trigger is activated.If welding gun trigger is activated, silk feeder starts and the source of welding current supplies
Answer electric power.If welding gun trigger is not activated and waiting time delay is at least equal to the retraction set in user interface
Time delay, then automatic silk retraction program retraction welding wire.On restarting the ability of welding operation during retraction delay period,
Similar explanation is applicatory.
