I'd just bought a welder like that. 20+ years old. Hadn't run in quite some time. A lot of cleaning! A few dent fixes. A fresh tune up. What I like most about it is it's a regular carbed engine. Most of the ones we use at work are fuel injection. Circuit boards are replaced frequently. And these welders are big enough to burn 6mm rods. Thanks for the video. It's on my maintenance list.
What generally makes those circuit boards go bad? I bought a trail blazer that only has 10 hrs on it , I didn't want to spend a bunch of money on a new one just to see it fry , I have the old board to repair if possible , if the price is right , but I need to address the problem first.
@@keithsharratt3402- To be honest, I really don't know what happens to them. I'm guessing it's the variable amperage while welding and running the fuel injection system?
@@gregwesterman2115 Thanks for the reply. I bought it as is , I needed a motor for my bobcat 225 , Onan took a dump , I'm going to see if I can rebuild it first, acts like it threw a rod , I was thinking I could swap the Onan for the Kohler from the trailblazer but it's fuel injected, I like to swap it to a carb , might be more involved than I want.
you will see a band of wires going from the generator to front panel. There should a wire that’s marked A1. There is a section on this wire that has a connected diode attachment with red/pink male and female connection. Check that diode. Bought 2 old miller generator welders for $500. One needed a coil and starter and the other was doing the same thing as yours. After running electrical check I noticed that this diode/resistor was fried. So o pulled one of the other machine and i haven’t had a problem with it since let me know if that helps

@@keithsharratt3402 - I truly wish you the best of luck. I think I just got super lucky with mine.

Thank you sir.
Thank you man, tried this and it fixed ours. I appreciate you sharing your knowledge.

Thank you, mine has grooves on it too, will try sanding it
Thanks for Sharing this Information.....my Welder is 225NT but Barely sparks, and electricity is Low.......
My bluestar is the same low on wattage.
Luck good job 👍
Sling blade fixed it
My bluestar wlds just not as it should
Hmmm just put new carb on it no power coming from a outlet s 0 volt!!!
