Jack,
Thanks for the post. I will reply point by point.
1) Sure, we could but then again we could charge a lot more for this machine...say 2 grand? Sound good to you? Give us another few hundred, and we'll work on it.
2) The color coding is fine, and in reality isn't all that unusual. Its not illegal. With manuals, and a staffed tech support line, that are manned, an answer is but a call away.
3) Actually the fan noise is fairly quite all things considered. I can tell that you are not used to welding or welders in general. This is a quite fan all things considered. The designer of the unit is actually a lot more experienced than you could imagine, and its easy to armchair a product like this. MANY MANY US welders do NOT use fan on demand. The few that do sacrifice duty cycle. We have discussed this many times here. For us, it is a closed discussion as we want the duty cycle over a little noise. This is the most compact 200 amp MIG on the market. Its a revolutionary achievement and I'd say the designer has made an excellent product. Who really cares about a little wind noise? Its a welder used in a much noisier environment.
4. If you won't be using the standard rolls, then you may have over bought a welder. 10 lbs won't last two days in my shop. This is a 200 amp welder, not a 100 amp flux core. At 200 amps, wire doesn't last long. A roll of wire if it does oxidize will usually oxidize the first wrap or two...After that, they should be a bright as a penny. Most un-coated wire has a slight "coating" designed to resist rust. Also, you may not be aware, but the copper in the wire, is used as a deoxidizer during active welding...It's not part of the weld material, so unless it rusts through the copper its not a problem. Anyway, as I said, if you spool off a few feet, it will be as good as new. I have been welding for years, and never had an issue with any of it, even if it was a little oxidized. If you are doing code work (and from your post I'd surmise you are not), then it MIGHT be a concern, then again, if you a doing code work you'll be using a lot more than a 2 lb roll on a project. Overall, its a fairly moot point.
5. Playing around and putting a foot pedal on the unit is not advised. This is not a cheap import tool. I can assure you. There are digital encoders under the panel, and not pots. Don't try to adapt this unit in any way...I mean it. Warranty is instantly void. This unit is not like our other units that have some room to make changes. Unless a tech tells you to do something, consider it off limits. We understand some people may want a foot pedal. Its not a current option. But the way the unit works is like most DC tig units...with lift start and a fixed amps. That is why it has 4T control.
6) See above, its a digital encoder. This unit is a digital welder, and microprocessor controlled. Again, DO NOT MODIFY THIS MACHINE IN ANY WAY UNLESS INSTRUCTED. Pulse MIG is much more advanced than a "rudimentary" system.
7) Again, do not modify this machine. HF will screw this machine up...or any MIG process machine. This is not a tombstone, and not even close. We understand what a HF box is...its used for overlaying AC with a HF current for transformer welders who do not switch fast enough to sustain an arc and for starting an arc without contact...Do not use this or even try...or you will not be happy.
I don't mean to take a negative turn on this...but this unit is a VERY advanced machine. It is a VERY well designed welder...and its operating at peak performance...This is not some cheap ebay special unit, and is completely unique and from a special factory that produces high end equipment. It is not some Harbor Freight crap mig that can be modded according to some techno- guys whim.
