Possible new logo for Everlast ? What you guys think ???

[performance]

Here is our current logo. I think we have dressed it up and it looks pretty good now. Underneath, in the white box, we can insert the unit name or other information as needed, as you will see on some of the panel faces on the newer units.

The good logo, it is useful to me
(I will decorate with it the cart)
Thanks Mark.

That new logo looks nice, but I dont really see a need to change. The current logo is dead simple and I like simple.

Looks good to me. Keep it simple color would be good. Frankly I like the current logo it's simple and clean.

Basically what I'm thinking.

Maybe put the line "IGBT inverter technology" under the company name in a smaller font.

I, for one, could not even tell you what IGBT means. Maybe something with those letters expanded in a smaller font beneath it. ???

Insulated Gate, Bipolar Junction, Transistor -> basically two transistor technologies (MOSFET and BJT) combined into a new technology created for high current switching circuits...

EDIT:

Just to clarify why IGBT technology is better than MOSFET technology, high current MOSFET's have a very large input capacitance that takes time to charge. This extra charge time creates losses (heat) within the device at higher frequencies so it is limited in its high frequency operation. High power BJT's require lots of base current in order to saturate, so BJT drive circuits have increased losses. By connecting a MOSFET as a driver to a BJT, in a darlington configuration, a much smaller MOSFET can be used at much higher frequencies to drive a BJT that can handle the power at those frequencies. Higher frequencies allow much smaller energy storage parts to be used which saves on losses (heat) within the box...

These newer inverter based machines (TIG, Arc, Plasma) - they are all MOSFET or this IGBT stuff?

I seem to recall someone teaching me once that inverter machines do not pull power from the wall until you actually weld with them, unlike the old school types that had big transformers inside. Is that true, too?

Lots I don't know, huh?

Everlast uses MOSFET's in their low end boxes and IGBT's in their high end technology boxes.

Transformer technologies have losses when magnetizing the core when the box is idle, and both resistance and reactance losses in the windings and core when being used -> these losses can be fairly high.

Inverter technology has very low switching losses when idle, and fairly low switching losses when heavily loaded, so the inverter does consume much less power than the tried and true transformer technology.

However, the transformer design is very robust, while the inverter technology is not nearly as robust -> nearly every trade off has some disadvantage...

Before I drop this topic: MOSFET and IGBT would be the Inverter technology, correct?

If not, what would be advantages/disadvantages of the inverter compared to the MOSFET/IGBT machines?

These small answers are much more educational for me than trying to read the literature that I walk away from scratching my head.

Inverter technology by definition means taking a DC input and creating and AC output, which is what is happening after the wall AC V is rectified. This technology can use MOSFET's, BJT's, IGBT's, and/or a few other semiconductor device types.

I believe Everlast only makes inverter type boxes, but Mark, Mike, Ray, Duncan, Oleg, etc... would know for sure.

You could tap into the great minds of everyone in the Everlast Welding Forum. Just have anyone interested in helping out the company make a sketch, design something on a computer, whatever the method, just upload to their design to the site. (This could be prime opportunity to open up another contest)

Go for it! Unfortunately, I have zero artistic bones in my body...
