We did this years ago. Lincoln power wave I400, deluxe analog interface, and a power feed 10 R.

Was about $10,000 for all. All from Lincoln. Complete plug and play set up. everything just plug in and was very simple to get up and running quickly.

To check for outside air currents you can tape small pieces of cardboard near the weld to see if it helps.

Sounds more like torch angle or travel direction to me.

I have also found it very difficult to find free information on this subject. I have been tasked with writing a risk assessment for a robot built in 1999. Have been quoted $9,000 for an assessment from a well known safety company. The RIA has some publications available to purchase for this project.

The publication we are looking at purchasing is called 360 Robot super safety bundle.

There are many standards referenced, and the means to create an assessment are included.

Ours is set up to run from the home position. We don't use it unless a serious crash occurs.

Usually a clamp left open or some other operator error. If you use it all the time be prepared to touch

points up all the time. fanuc techs don't advise it to be used that way.

Torchmate is a program that comes with the controller as an option.

It is not that helpful unless you have a major crash of some sort.

Should not be enough voltage to burn the plate. Are you calling it from your program list?

Making sure the toolng can be located in the cell exactly the same in all the cells.

The location of fixturing from the test cell to the production cells will be critical.

Switch to .035 wire or smaller. Delete the wait at the start, and delete the weave.

Switch to 90/10 or 95/5 gas mixture. I would try trim .85 wire around 200 and travel @ 30 IPM to start

.

You may have no more available memory left. But also one time we had corrupted memory.

We had do do a back up to get rid of the corrupted memory. You can try and backup your programs to a memory card or laptop and delete some from your controller then try it again. The Fanuc tech told us that somehow blocks of memory become corrupted and cannot be used.

Dissimilar metals seem to cool at different rates. Pre and post heat may help. You may have to add filler designed for this type of application.

I program off the teach pendant on old robots that still work great.

Some of my early crashes were pretty spectacular. With programming with the operators we have

now, my programs are getting the job done, with as much error proofing (idiot proofing) as i possibly

can. Have had many more crashes caused by the operators lately.

The 455M may be anolog, the 10r is digital. The Lincoln I400 is the replacement and is digital.

Good morning

Yes the cell has been there since 1999, there has been no risk assessment ever done on the cell.

Yes it is for our own safety program. Was suggested by our workmans comp consultant.

Original integrator has declined to do one for us even if we paid for it.

If anyone has had to go thru this, any guidance would be greatly helpful.

Does anyone have any advice about how to do a risk assessment on a Fanuc mig welding robot with a RJ3 controller?

The unit was bought in 1999 and there was none required by the integrator at that time. Now we must get one done

to comply with our safety program. I have asked the original integrator to do one but they say they are unable to do it to today's standard.

We are very safety driven here and looking for help getting this done.

Without knowing what your process involves, here is how we do it.

1 Turn on the teachpendant.

2 Make sure step mode is on, and speed is @ 10%. You will have to hit the reset button for the alarm.

3.Either press shift + back key to back up a line, or Use the axis keys to manually move whatever crashed away from whatever it crashed into.

4 Clear whatever was the cause of the crash, for us it is normally a destaco clamp.

5 If you manually moved the robot, hit the shift + back key until you get to a spot before the crash happened.

6 make sure the reason for the crash is now removed.

7 turn off step mode, reset teachpendant to 100% turn off teach pendant.

8 Restart robot from the operator cycle start button.

Every time you have a crash, you need to do everything you can to insure that it will not happen again.

Many of us work at places that do not have proxy switches on every clamp, some fixtures we use have 30 destacos on them.

It is in the best interest of the robot to have capable people operating it.

the robot only does what it is taught to do when someone tells it to do it. I now program air moves well above clamps that could be left open.

If this unit is brand new, I would ask the the manufacture to take a look at iy.

I just wanted to clarify my last post. Was saying to check where the cable hose that goes to the welding torch goes into the wire feeder was pushed all the way in and the screw was tight. We have had that work its way loose in the past. Glad you are up and running again.

Is the hose lead where the cable hose mounts into the feeder push all the way into the receiver on the wire feeder and the screw tight.

If it is not pushed in all the way the gas ports will not line up.

Use a name brand alkaline battery, don't skimp. Been seeing posts about batteries going dead and losing master.

We never!!! turn the power off to our robot controller, we just power it down with the off button.

When you turn off the large switch used to lock out the robot to maintain or repair it, it goes onto battery back up.

the only time you want to be on battery backup is when the power is off to your building.

Check the selonoid wires on the back of the feeder. or could be a bad selonoid. This turns on the gas flow on and off.

They sometimes wont work when the become covered in metal dust also.
