Yes, I agree with the advantages. How would it be different from a drill press that already has infinitely adjustable speed (not stepped pulleys)? If it's the Klutch 17" floor model- I don't know what they use for speed control. The VFD is a bigger gain for users having to change pulley belts....

Yes the old post. Changing pulleys for speed control is not half as good as twisting the POT on the fly. Just like welding with low too of an amperage- we start slow, and put a slow rate of down pressure on drill. It generates heat and ruins the bit. Better if you can run a higher feed and pressure ...

I got the idea from a machining forum years ago when treadmill motors were a dime a dozen. The motherboards cost more to replace than to replace the worn unit- so DC motors were easy to get. This is an easy way to get around the DC wiring to AC current and it works slick.The belt hardly ever slips. ...

Why do it? After having it for 10 years the 4 best uses for spending money and time to fit a 3 phase motor on your existing drill press: -Improved cutting speeds for steel to cut a hole and preserve the drill. -Actually being able to drill stainless 304 and 316- almost like steel. -Use of a counters...

I got the amperage slider with the 221 for 2T. Later read where they recommend the on/off button for 4T lift arc, pulsing and spot welding- not the amp slider. They packed a lot of features in the welder, this must be a trade off, which is fine.

Thank you. Will submit some pictures when I figure it out. Not using the CP so it's google photos to the forum. Looks similiar to my KTM forum. The owner has a very basic site and google is a very basic freeby. Found the upload attachments tab. Looks like 640 works fine. Home project now more than 2...

I have built metal railings, driveway gates, some outside storage from steel and had it galvanized. Home improvement basically with a 40 yr old Miller econotwin. No thermal protection and shorted the main transformer spend too much school time welding aluminum in the shop. Shop junky forever- before...

Hobby welder with new HTP 221 Invertig. Found TNT on utube with other welding sites and always looking for the simple tips for better garage time.
