Miller Maxtron 450 set up questions Please help

admin

Hey guys i finally found the machine that i was looking for a miller maxtron 450 with a plane jane S-64 feeder..The guy i bought it from didnt know anything about it, other than the history of the machine It came with a maxtron cart has a tweco black gold tig torch with miller hand controls as appossed to the foot pedal, a miller 251D-1 high frequency unit a stick electrode holder and ground clamp all the copper leads its a great set up. I got it back to the house and took everything off of the cart to clean it up took all the panels off blew it out (it was spotless to begin with on the inside only outside had an inch of dirt and dust) i had to wire it up single phase for my shop with all four jumpers.I hooked the positive up to the feeder i hooked the 14 pin to its receptacle and the ground to the work i then set just the feeder up to mig carbon steel without all the extra stuff When i got done i read the miller manual and set the four toggle switches to mig So far ive done everything by the book. i turn it on and proceed to start welding and nothing the only way i can get it to strike an arc is to crank the cv inductance to close to 90 and even then about the most voltage i get is 12-15.5 volts the actual voltage/amperage knob on the maxtron wont adjust the machines output am i having a brain fart, hooking up wrong or what. id love to find out what im doing wrong ive heard these machines are great and this one is like new its never seen a robotics cell or factory the guy ventured to say that it has less than 5 hrs of actual arc time and the way the machine looks i believe him it looks like it was bought used a few times and stuck in a corner for 10 years So if you can help me please speak up i need all of it i can get im used to the deltaweld 452 at work it has 2 knobs voltage and wire speed this is the first mig machine ive owned with a seperate feeder any help would be great thanks guys...
