Re: Miller 330 A/BP - DCEP (Reverse Polarity) No Output

I never saw the original post, but glad you got it working! The HF start isn't the most robust on the 330 A/BP, but the arc is very smooth...great machine to learn on. Not only that, but you stole it at that price! :mrgreen: Thanks, definitely has been a learning process putting it back together an...

Re: Miller 330 A/BP - DCEP (Reverse Polarity) No Output

On those machines (and ones with similar contacts like my Bobcat 225nt) it's a good practice to move through the contacts every time you use it. It's even in my Bobcat manual to do that. Keeps them from getting corroded I suppose. So before I went out and started buying all the TIG equipment, I was...

Following up on my post:

Cleaning the points on the contact board, switch - polarity (S10) did the job. I cleaned the points with a wire wheel/sprayed them with electrical parts cleaner. I am now getting output on both DCEP and DCEN. Now on to getting it set up for TIG/AC welding!

Miller 330 A/BP - DCEP (Reverse Polarity) No Output

Hello All - Noob here, working on getting a miller 330 A/BP up and running (bought it in an auction for $60). Got it home, cleaned off connections, wired it up and plugged it in. Nothing kicked on. Did some troubleshooting and replaced the F2 fuse per the manual, and bam, machine and fan kicked on. ...
