    Re: Trailblazer 44G No Voltage

    I know when I messed with the Airco (Big 40) after my experience with my Redface I thought it was more a transistor radio than welder. It welds good but IMHO the puddle seems more agitated than the SA. I might be wrong but that was my impression after doing side by side welding with both machines.

    I just reviewed your thread and realized we haven't had you test for rotor winding resistance as yet. If the exciter rotor winding is open you're not going to have any output regardless of the voltage at the slip rings.

    To test the rotor windings, lift the brushes off the slip rings and probe between the center ring and each outer ring. On the TB 44G I believe you should have +/-45 ohms between the center and rear rings and +/-12 ohms between the center and forward (toward engine) rings.

    Correction - on the TB 44G rotor resistances are 48 and 13.6 ohms for the exciter and weld windings respectively and +/-5%.

    The exciters on these guys are notorious for shorting out. the plus is there easy to rewind and the wire diameter is a common size.

    Thanks gentlemen for the information.

    I will have to put off further trouble shooting until I get back from a 2 to 3 week vacation. The wife's family, from France, seven people, arrive this week. I have to drive up to Chicago to meet them, we're going to visit Wisc, the U P and Sault Ste Marie.

    Hopefully we can figure this out when I get back.

    Gentlemen,

    I made it back about ten days ago. We had a really good time. 37 years ago I married a French girl.......a bunch of her family came over for two weeks.......visited Chicago, Wisc, and Ontario.

    I haven't been able to do the necessary testing that Duane suggested, there has been so much rain here during the past couple of weeks. The temps and the humidity have been out of control.

    I will report my findings hopefully the beginning of next week.

    Dave S
