  • Hobart Handler 180 wire feed issue

    Bear with me on this. I am a novice at best. I was just trying to weld some 18ga tubing and kept getting a lot of popping. I figured it was due to wire speed being too high so i adjusted and same thing. Adjust again and same problem. So i looked at the gun as i hit the trigger and the wire comes out at the same speed (it seems) from the lowest setting all the way to the highest setting. This has never happened before. I have probably only put 3 spools total through the machine in 5 years.

    Verify this, perhaps even with a linear measurement per ten seconds or something like that.

    You will get expert advice on what to fix by Monday most likely.

      My welder has wire feed optiona from 1-10. At selection 1 in 10 seconds 7’ 1/2” of wore came out. And on selection 10 i had 7’ 2” come out in 10 seconds. I was using the stop watch on my phone so give or take a few tenths with time, but they are basically putting out the same speed.

        Yep, sounds shot. The Hobart Expert (probably on Monday) should know which part is the culprit.

          If the speed does not vary as you adjust the speed control then we will need to check the potentiometer with a meter. It should measure 0-50k ohms from the center to each outside. If tests bad replace, if tests good the control board will need replacing or repaired.

            Thanks for the reply. I have no idea how to test that or even what to use. Is there any step by step instructions online?

              No service instruction online and without a volt ohm meter you would not be able to perform any testing.

                I have a volt meter i believe but i have no idea where the parts to be tested are on the board. I assume there is not a diagram anywhere either?

                  Diagram will be in your manual on in the manuals we have available on our website under the service and support tab.

                    I have the manual and have located where the potentiometer is per the diagram. My extent of using a volt meter is checking AA batteries...so i literally have no clue what im doing, or even what setting to use. Do i turn the machine on and touch the back of the pentiometer? What should i be touching? Do i need to press the trigger when i do it? Im not trying to be a pest, but i have never done anything like this before and i just want to get this fixed so i can finish my project.

                      Have you Googled or YouTubed "testing a potentiometer?" I have to believe there are several good articles and videos already out there.

                      To test it, you will not want the machine plugged in. You will use the Ohms (Resistance) portion on your meter, on the contacts on the back of the pot[iometer.] Measure the values while turning the knob.

                        I found one video that somewhat shows how to test the pentiometer. I was mistaking i dont have a multimeter...had to buy one today. No instructions with it so i guess ill just have to figure it out. Cant get the cover off my welder. All my sockets and bits wont fit in the crevices. I guess ill go buy some more size sockets tomorrow ans try it again.

                          Ok so I put the multimeter on the setting shown and when touching the middle and right contact (if you are looking at the fromt of the welder) at 0 wire speed setting it read 47.6 and at 10 it read 0. Touching the middle and left contact at 0 it read 0 and at 10 it read 47.6.

                          Does this tell what i need to know?

                            If it read 0 to about 50k ohms as it was adjusted then the pot is good and the problem is in the control board.

                              Thanks Keith. Does the setting on the multimeter look correct?

                              i assume replacing the control board is the least desirable option of the 2. Do you have any idea how much that part would run me?
