Jakeru, you just added a grand to the cost of the machine! Overall the basic design and parameters are going to closely match the EX/EXT units.

The cooling system will not change. It is still the same High Output fan design we use on all our units. It's not as much an issue with an improper blade design. It is aggressive to move a lot of air. This isn't your laptop with a low volume fan. You ask for duty cycle, we give it. But we have to give it around a design that works for us.

We have deleted the water flow function sensor on the unit. It is a cost item and an extra circuit to give issue. IF you want to prevent damage, simply use a fuseable lead. It is likely we can wire the plug to switch on but... This is a minor issue and the responsibility of the customer to manage the flow. Any damage resulting from not turning the cooler on is the operator's fault as it is and not part of the warranty.
The switch will not be added on the front. The plastic molds are cast. It is VERY expensive to make any changes to the mold. There was not enough room as it was.

The pulse and AC frequency range will be oriented around practicality and stability of the unit and not wild extremes that are of limited value.

The output is going to be 250 amps. That is the practical "target" limit we are shooting for in this unit on single phase. It's a range that works for us in our sales figures. If you need more, the 320 EXT is available now.

The super flex and all that stuff will be available as an additional purchase as of now.

We made the decision to drop the amplitude off of a variety of inputs. I did not agree with it, but it is gone. The basic features are already in development, so we are not able to make much changes at this point.

What about high frequency start? Will the machine have a HF startup like the 250 EX or the more robust design like the 250 EXT?

The 250 EX has been changed as well so it isn't the same type points being used and should be being phased in.

[CGCINC]

So will there be a kit you guys sell to change the older model 250EX points to the newer type system?

Honestly, I am not sure if they are 100% compatable with old style. Any kit would require some soldering.

Mark, a very good, well thought out wish list was presented, defensive replies like " This is a minor issue and the responsibility of the customer to manage the flow. Any damage resulting from not turning the cooler on is the operator's fault as it is and not part of the warranty. " are very abrasive and will only cause friction.

The built in water flow protection was a great feature on the 250EXT, I hate to see it go.
Air noise is another issue that probably could have been addressed in a complete new design, instead of trying to convince people that large air volumes have to produce large noise.

So, what are you going to do with your 250 EXT?

I'm not sure yet, I'm sending the 250EXT back, but I'm going to have to hear a few more good things about the 255EXT before I decide to try it.

I am going to ship my 250 EXT back and go with the 2550 EXT.

I was told by Oleg that the 255 EXT will take a range of pots from different foot petals 5K,10k,20k…, as the new welder has built in electronics to adjust for the different pots. This is a cool feature if it works well. The main issue will be rewiring a foot petal to accommodate the Everlast plug.

[Rambozo]

Or perhaps a wireless receiver plug?
