Can't set power...

[mariotig]

Hi fellas,

I've read a number of forums, and I am still at the starting point.

I just acquired an Everlast Power Pro 205. I am having trouble with the main amperage control. Apparently it is always starts at around 100 amps. That's with or without the foot pedal connected. After reading some posts, I'm pretty much ignoring the readout on this machine and going by what's happening to my puddle.

The way I can tell is the electrode is getting too hot and my puddle is way to large. No matter where i set the control, I get the same result.
Tried steel, stainless, and Aluminum(on AC with ~100Hz and 70%). My shielding gas(UHP-Argon) is at 20 cfh. Used 3/32 Thoriated with sharpened electrode(professionally sharpened) and No.7 cup. I also tried 1/16 electrode...same thing!

I am wondering if the rheostat (control knob) is bad?

Has anyone had a similar issue?

I'll be calling Mike at Everlast tomorrow(if open?).

Thanks,

Love this forum...lots of helpful info!

Start, by setting your start amps and end amps to minimum. Turn off slope.

And turn your cleaning to 30% of electrode positive, not 70%. And please read the manual as it discusses these items and more. Make sure the pulse is turned off as well.

Mark,

Ok...I'll give it a go. I don't have a pulse switch. I guess just turn it down to 10%.
Why would the current be so high, in general? Even though it's turned down to ~5 amps?

Here's a pic of the front of my unit:

I'll let you know how it goes.

Any idea what year model that is? Very odd that there is no low-high-off switch for the pulse. The front panel doesn't match any of the online manuals that I can see. The '09 is the real old version, but the '12 has a few more controls, including the low-high-off. So I guess yours is in between those two? Any chance of having someone watch the display while you are welding with the foot pedal to see what is shown?

That's not a new unit for sure. That's a Oct -Dec 2009 unit I believe. You must have purchased it second hand or old stock. Turn the Pulse amps down all the way if no switch.

Mark,

Yes, it was second hand... It looks to have been manufactured in 2010. So, it could be an '09 unit.
