In picture shown in 4, for example, user's pressing operation button etc. selects the project of " welding current ", user can also be grasped
Make to change the setting value of welding current.
<The explanation of the storage method of welding condition>
Then, illustrate that welding condition storage is arrived internal storage 21 and external memory storage by control panel 20 in weld job
151 method.Fig. 5 is illustrated welding condition storage to of the method in internal storage 21 and external memory storage 151
The flow chart of example.Here, inserting external memory storage 151 to control box 15.Additionally, user is before weld job is started or welds
In operation, the setting or change of welding condition are carried out beneficial to control box 15, welding condition is shown in the display part of control box 15.
In addition, user is when weld job is started, the servomotor of position, the speed of welding torch 11 or chassis 14 etc. will be controlled to connect
Recover the grade of welding torch 11 origin.
First, if user presses the behaviour for starting weld job for accepting among the operation button that control box 15 possesses
The operation button of work, then control panel 20 accepted via control box 15 welding start operation (step 101).If here, not having
External memory storage 151 is inserted into control box 15, then the display part in control box 15 shows mistake.If control panel 20 has accepted weldering
The operation of beginning is connect, then controls the action of welding torch 11, chassis 14 etc. based on welding condition set in advance to start welding work
Industry, and moment (hereinafter referred to as welding start time) and the welding bar for having started weld job are internally stored in memory 21
The setting value (step 102) of part.
Then, control panel 20 is internally stored when have passed through predetermined 1 time from welding start time every time
The welding condition for weld job is stored in device 21.Here, control panel 20 determines whether to have passed through for the 1st time (step 103),
When have passed through for 1 time every time ("Yes" of step 103), the welding bar for weld job is internally stored in memory 21
Part, the welding condition (step 104) for being set at the corresponding moment.On the other hand, if not by the 1st time (step 103
"No"), then control panel 20 does not internally store welding condition in memory 21.
Additionally, control panel 20 from welding start time when predetermined 2 time has been begun to pass through every time, in operation
The welding condition that internal storage 21 is stored is stored in the external memory storage 151 of case 15.Here, control panel 20 determine whether through
Spent for the 2nd time (step 105), when have passed through for 2 time every time (step 105 "Yes"), having read storage at that moment and existing
Welding condition in internal storage 21, stores the welding condition (step 106) of reading in external memory storage 151.Here, outer
Portion's memory 151 stores welding condition in the form of master data and subdata, as subdata, with every the moment of the 2nd time
Used as sampled point, storage welding condition is used as the file split by sampling time point.Also, power supply disconnect etc. and cause it is different
When often stopping, stored subdata is not deleted and is to continue with portion's memory 151 outside and is preserved.On the other hand, if not passing through
2nd time (step 105 "No"), control panel 20 does not store welding condition in external memory storage 151.
If here, for example, the 1st time was set into 1 minute, was set to for the 2nd time 5 minutes, from start time is welded
Welding condition internally just was stored in memory 21 every 1 minute.Additionally, transmitting inside to external memory storage 151 every 5 minutes
The data of the welding condition that memory 21 is stored, store in external memory storage 151.
Then, control panel 20 determines whether to have accepted the operation (step 107) for stopping weld job.Here, for example, with
In the case that the operation button for accepting the operation for stopping weld job being pressed at family, control panel 20 is received via control box 15
The operation (step 107 "Yes") that reason welding stops, stopping welding torch 11, chassis 14 etc. to stop weld job.Additionally, control panel 20
Internally storage stopped the moment (hereinafter referred to as welding the stop timing) of weld job and in moment setting in memory 21
Welding condition (step 108), terminate this handling process.On the other hand, if not accepting the operation (step that welding stops
107 "No"), then step 103 is transferred to, then, control panel 20 is every storage welding article in the 1st time internally memory 21
Part, welding condition is stored every the 2nd time in external memory storage 151.
Additionally, in the method shown in Fig. 5, user presses the operation button for accepting the operation that weld job starts,
So as to start while weld job, also start to store the treatment of welding condition, but be not restricted to that this structure.Example
Such as, it is also possible to be separately provided for starting the operation button of storage.In addition it is also possible to welding current, weldering when being started with welding
The rising edge of voltage is connect for opportunity, starts the treatment for storing welding condition.If in addition, by pressing the behaviour that weld job starts
Also start the storage treatment of welding condition as button, be then prevented from user and forget situation or treatment mistake of operation etc..Together
Sample, is expected that by the operation button that user presses the operation for accepting weld job stopping, so as to also stop welding condition
Storage is processed.
In addition, interval, i.e. the 1st time, the 2nd time of storage welding condition can be changed by user.If for example, the 1st
Time is less than 1 second, then the data volume of the welding condition to be recorded is huge, needs to carry out long-time more than half a day in weld job
In the case of, whole resume cannot be left in external memory storage 151 sometimes.Additionally, data volume is huger, can more lose
