Bored, need a problem I actually can't figure out

Anything, welder related

I have a Millermatic 211. It has the smooth start feature where the feed starts at a reduced speed for a second then up to set speed. This is used the help eliminate hot starts and spatter. It works correctly when using the 110v plug. But when using the 230v plug it only works on the first trigger pull then not again unless I turn the welder off and back on, then only on the first trigger pull. It worked correctly one day a few weeks ago and then back to the same. I talked to Miller and they sent me a new PC1 card, but it didn't fix it. it doesn't matter if the wire feed clamp is on or not. It's not a big deal, but would be nice if it worked the way it should. Well you asked for it.

Hmmm, first off, is your ground clamp the stock miller, the one that has a couple of u shaped knubs at the end. Kinda shall we say brass less.

With the machine off, press the trigger, turn the machine on, wait a couple seconds trigger depressed, release, and re trigger. Is the slow start back or does it remain the same?

[labmaster02]

The clamp has been changed but has nothing to do with it. Tried with the trigger and turning on. The over temp light was flashing but still the same. I think you are thinking of the older machines that had a programmable feature the would adjust the feed speed with the voltage. This is a newer machine serial number MB290644N.

Remember the strange part is it works fine with the 110v

Actually the improper ground clamp sets the tone on how the welder works.

As for the pressing of the trigger, many welders pulled a reset when this is done, not just the older models. Often this tid bit of information was not posted anywhere.

As for the 110 to the 230. basically its a whole different program the machine is using, so you simply can't compare one to the other

OK, with the gun trigger disconnected from the machine and with a paper clip or a piece of mig wire, jumper the machines trigger terminals, does the drive start slow each time, or is it slow first and speed up the other times.

Cruizer,I have a number of 30A control cables that I would like to figure out if they are servicable or not.I do not know the history of the cables but cannot see just blindly tossing them in the trash when replacements are 300 plus.
Short of a megaohm meter(which I could afford if I could build a couple of 30As to sell) is there a way to see if they are good or not?

[cruizer]

When I test the 30A's I just plug em into a WC-24 and Miller PSA power supply.

As for control cables, they seldom go out, however the pins in the plastic AMP pins tend to pull out.

Testing the cables themselves can easily be done with a resistance meter (OHMs) though.
