  • miller 250 dialarc problem neeed help

    I was welding heavy alum when my touch lead stated to leak. I got a different
    welder for the shop and brought the old one home, where I repaired the leak,
    by gluing another peace of hose over the old one. it holds fine. Then I hooked it up
    and tried it, I am on dc straight and set to start, it wont start a arc unless I touch
    the tungsten to the metal and pull it away it give a very small arc and then nothing
    on continuous it will hold an arc but it looks funny and will only melt holes in my sheet metal . I have reset the points to .010, and I hear and feel gas coming out
    of the touch. Any ideas what the problem could be. thanks joe

    Try it with a "Known Good" torch.... that one may have cooked when it started to leak... did you run it dry..??

            what model...HW-20..??

            most brands had used the same numbering system till recetly...

            now everybody but ESAB has made up a brand new numbering system... including Weldcraft/Miller and CK...... dumb move...
            the old system allowed for easy parts interchangability..

            can probably find an equivelent water cooled torch in the $150-250 range...

            do yourself a favor and get one with the rubber superflex hoses... they are tougher, more flexible and they do not get stiff in the cold weather like the standard Black PVC hoses.. but they cost a bit more..
