Thanks for that will look at putting a non return valve in aswell

i am looking at a way of calling a output on only if the main program or robot has been inactive for 3 hours or more, just want to add a gas purge if the robot has not been used for a while as when we restart the arc welding robot the first part off is full of porosity due to lack of gas. i know i can put a non return valve on gas pipe to see if that stops it but i,m also curious to see if this can be done in case the return valve does not work.

Not very clear but may be what your looking for

You were right, SHIFT -ON AND SHIFT-OFF did the job perfectly, i was able to use it to change the position of the robot dipping into the anti spatter paste numerous times. Instead of dipping 16 times i managed to do shift on and increased the times the robot dips into the anti spatter paste 80 times before the the paste needs leveled again. Thanks for that Massula
And there was some things missing, i also did the program from scratch and rearranged everthing.

Well, never saw this exact application, but I think You can achieve some results with GETPOS, SHIFT-ON and SHIFT-OFF commands.

An example of a robot program I can create that will do what I want. little example
<< COMMAND(S) >>
<-> Begin of Program
TOOL = 1:TOOL01
(+) MOVEP P023 90.00m/min
(+) MOVEP P025 90.00m/min
[ ] :START
INC GB#(2:REAMER COUNTER)
IF GB#(2:REAMER COUNTER) < 17 THEN JUMP REAMER ELSE JUMP RESET COUNT
[ ] :REAMER
IF GB#(2:REAMER COUNTER) = 1 THEN JUMP LABEL0001 ELSE NOP
[ ] :LABEL0001
(+) MOVEL P005 90.00m/min
JUMP END
IF GB#(2:REAMER COUNTER) = 2 THEN JUMP LABEL0002 ELSE NO

Got a program to achieve what I wanted but the long way round I think .

Shunt was arcing out

Anyone have a sample program I can have for reference, thanks

Will have a look, thank you

Looking to create a programme for a mig robot to dip the nozzle into anti spatter paste, I am thinking of putting a small square container inside the weld cell and after the nozzle clean I want the robot to dip the nozzle into anti spatter paste but each time it goes in I want it to dip into a different part of the container so need a simple programme that can offset the points and then repeat.

Will let you know if we find anything,don't think fit up is the problem as why does this not happen all the time. Built over 200 parts today and only two failed, will post more as we are looking into other things.

This robot applies 8 welds, this only happens on the very first weld applied but can happen at any time. There is a slight gap of 1.5mm and the material is 2.9 to 2.9. This alarm happens because ultrasonics have found this weld failing quite a few times so we reduced the current low to 3% on this sequence so the robot will stop so we know this weld has failed and we can scrap the part off. Operator ran over 300 parts and we had six failures ?. Material is also coated and the robot has tried to weld it but there is only a very small nugget. We have another cell which runs the same parts and a cell which runs the opposite hand to this all with the same settings but with no failures.

Poor intermittent spot weld , robot does not stop but this alarm is evident. Unable to trace fault code as it says it is the weld controller but I don't have a manual
-
Anybody have any experience using pulsed welding with the panasonic robots, Just some tips or settings if possible.
-
Still ongoing as been very busy lately so unable to get a look at the robot as yet
-
I have set up a tip check program and noted the axis angles down, I will do the same for the arc starts and arc ends when the cell isn't running and get our facility on to check for backlash.

[/img][/img]Thanks for the reply, some good things in there and I will check them all as soon as possible. I am just using basic mig welding nothing fancy and I will be back in work on Tuesday so will let you know how it goes and if I find anything.

We are recently having a lot of problems with touching welds up on one of our robots, we have two robots welding at the same time on the same part and we seem to be carrying out a lot of reteaching on just one of the robots. The welds seem to be moving and when we correct them a few parts later the welds need to be touched up again but we have no problems with the other robot. They both weld on the same jig which only turns twice for access and then they move over to the other jig and we have the same problem from the same robot on the other jig. Is there anything I should be checking as calibration ok and robot solid but cant think of what else to look at.

during a welding program I would like to switch to pulsed welding just for one weld and then switch back to standard mig for the next weld, is this possible. I have tried wpls on and then off but didn't seem to work. Can I set tawers 1 for mig and tawers 2 for pulse and select each one before a weld.
