Trailblazer 251 - Stick is dead

admin

Hi ya'll,Thanks for your help in advance.  I have a Miller Trailblazer 251 that will not draw an arc on the stick mode.  I have AC and the unit will instantly melt rod if I switch to the wire setting.  I only have the stick setup for this machine.  I have checked all fuses and and cleaned the cable connections to be sure but with such a good arc on wire I don't believe connections are the problem.  The id plate is missing off the machine so I don't have a serial number.  The unit was welding great and then quit like I had a ground issue but it won't even draw an arc directly on the ground.  Any thoughts would be appreciated.Thanks.

Reply:On further investigation there is no sticker with ser. # in the machine.  I have inspected the inside and find no melted or broken wires and all connections are tight.  There is a faint spark when you try to draw and arc on the ground but not even enough to excite the exciter.  Anybody have an idea of what to check next?Thanks
