HTP 221 took a dive yesterday.

Tweco may even make drive rollers for that machine. My old MM250, most of my drive rollers are tweco.

[ryanjones2150]

Trying again....

[ryanjones2150]

Still doesn’t look like it’s posting up. If you take a look in the last picture in my original post, you can see the clear stuff surrounding the IGBTs. If you touch that stuff, it sticks to your finger and strings out.

[ryanjones2150]

I tried to post a picture with the last post. Let’s see if this one goes through....

[ryanjones2150]

That’s about right. Keep an eye on eBay too.

[ryanjones2150]

Anyone have any idea what this sticky, snot like clear schmoo is that surrounds these IGBTs in their nifty little box? It’s something separate from the thermal paste, that’s there too, but this fills the void in between the components.

[ryanjones2150]

Right, but what was it you bought that is fried?

[ryanjones2150]

I just did a quick google search for Waukesha engine parts and found all sorts of places making parts for that brand of engine. Maybe one of them will have the part you need.

[ryanjones2150]

You should be able to get all those parts from your LWS.

[ryanjones2150]

I love those little saws.

[ryanjones2150]

I’d try to sell it through local outlets before I did eBay or something like that.

[ryanjones2150]

Ya I sent a pic to Wayne and he helped me find replacement parts. $20 for 10 of them, that gives me two and a half chances at getting it right!

The HTP folks walked me through some testing and are confident that slapping a new board in there is safe, so I’ll try and repair this one first...

[ryanjones2150]

Throw it up for sale for sale for $800 and settle for $500 and it’ll probably sell pretty fast.

[ryanjones2150]

I just ordered 10 apparently now obsolete IGBTs from Slovenia for $18. That gives me 2 and half chances to not screw it up. Just trying to find the gooey mess these parts are surrounded by.

Leo, that looks pretty close. Pop off the side panel and you’ll probably find Miller electric...

[ryanjones2150]

For that matter, I have a 7 year old broken welder with obsolete parts.

[ryanjones2150]

I don’t recognize that machine as a Miller, but it may very well be. If it is a Miller, it will say “Miller electric, Appleton Wisconsin” somewhere on it. If not on the outside, many of the internal components will be labeled as such, especially a machine of that age. They usually have a Miller...

[ryanjones2150]

I guess it depends on how quickly you want to sell it.

[ryanjones2150]

Whatever you get make sure it has replaceable batteries. Some of the lower cost ones don’t. On my Miller hood, it does not like off the shelf batteries either. There is a bit of a thickness difference between the Panasonic battery Miller sells and the standard replacement from wherever. I also have...

[ryanjones2150]

A level, a square, a string line, a jig....lots of ways to keep things straight. I don’t care much for using magnets, I prefer using squares and clamps.

[ryanjones2150]

Turned on my machine, turned on the argon, grabbed my torch lead and went to uncoil it and something went POW!! Breaker was tripped. Reset everything, machine was dead. Popped the sides off looking for something obvious, found what I thought to be a popped capacitor but it has since checked ok. Sent...
