  • spoolmatic 30a

    running my spoolmatic off my bobcat for first time today. ran good off my shop 110 (for wc-115a) but when I try to run the 110 off the bobcat it don't want to weld? feeds ok. doesn't seem to have enough current to weld though. (yes I have my fine tune amps turned up on bobcat) Any ideas? do I just need to turn up my amps?

    Do you have it set to CV constant voltage mode??

    for MIG you will want CV mode NOT CC mode

    and adjust your VOLTS not your amps...

      Yes I have it switched. Everything works fine when 115 is plugged into my shop. Problem is when I plug the 115 into the bobcat

        Could you post the serial number of your Bobcat 225G so we could consult the correct version manual... ??

        so we can make sure there are no switches in the wrong position..

        lots of times it is just a simple switchology mixup..

            Is the Engine set to "RUN".... so it runs full speed??

            NOT to "Run/Idle" where it will idle down

            and that CB3 & CB4 are not tripped

            See page #19 Fig 6-1

                You might also check 9-2. Auxiliary Power Troubleshooting Pg #33


                No output at auxiliary power

                Reset circuit breakers (see Section 6-1 or 6-2).
                receptacles.
                Press optional GFCI receptacle Reset button (see Section 6-2).
                Check fuse F1 and replace if open (see Section 7-4 or 8-6).
                Check plug PLG6 connection

                  crap........

                  Finally got back to it. I must have had something set wrong before. It ran great for a couple beads off the bobcat. Then the rpms dropped for a split second and everything went to crap. looked over and seen smoke(wc-115a). unplugged, shut it all down. pulled the cover off the wc-115a and the ground wire coming in is burnt. what ya think?

                    Rewired the 115v . Plugged it into my shop power. Ran fine. Cord never even got warm. Got a friend comin over tomorrow to check outputs on bobcat

                      I don't know about the smoke....
                      but is the positive lead ran through the wc115? It has a current sensor that when current is detected, it switches from run in speed to set speed on the gun (wire feed speed).

                      Does your have a contactor?
                      Mine did not, so I bought one that had a 24v coil and installed it myself, the bobcat has to be in run for my contactor to close when I squeeze the trigger.

                        yes the pos lead runs through the wc115, through the contactor. the issue is with the 115v power for the drive rolls. it runs fine off shop power but not off the bobcat. It did run fine, but the wires got hot and fried the ground wire when run off the bobcat

                            I would first ask if you have gone through ALL the troubleshooting steps in this reply??
                            AND the troubleshooting section of the Bobcat manual??

                            http://www.millerwelds.com/resources...597#post309597



                            If you have gone through all of it and still have erratic 120vac output...
                            you might have a problem with your Bobcat..

                              yes, I have checked all that I can. Nothing in the trouble shooting refers to the problem I am having, That is why I am having the outlets checked before I go any further
