Thank you Larry, Both for the effort you put into this evaluation, and for your (and your company's) willingness to share it here. I'm not too surprised with your conclusions... Every tool has it's place and purpose, and the marketing departments of many companies tend to inflate their claims for t...

WerkSpace, Thank you for your comments. I agree that there are improvements that can be made in the operating procedures that are recommended in the Multiplaz-3500 manual. However, for our testing we first test the torches as stated in the manual. My evaluation is also from the perspective of using ...

I am happy to see the interest in the Multiplaz (water/alcohol plasma) technology . I am even happier to see the rational discussion of its advantages and disadvantages on this website. I read all of the postings on the other sites about the Multiplaz-3500 unit (all 30+ pages of them) before I start...

The value given in the table for the weight of the Miller Spectrum 125C has a question mark behind it because there were different weights listed in different Miller publications about the unit. I checked with Miller and the weight for the current unit, complete with torch, is 31 pounds. In 2004 the...

CLARIFICATION Replace the sentence "Obviously, if the transfer were very efficient, the inner core of the plasma arc wouldn't be able to sustain a temperature of 8,000 to 20,000 degrees Celsius." with "Obviously, if the radial heat transfer were very efficient, the inner core of the p...

Correction:

Rather than say "cutting vertically sideways", I should have said "cutting sideways with the sheet vertical".

If this were a weld, it would be called a horizontal weld.

With regard to the questions about the composition and temperatures of the plasma; The central core of the plasma is, according to the Multiplaz literature, at a temperature of about 8,000 degrees Celsius. But the central core (the brightest point in the plasma) is surrounded by gas at lower tempera...

With regard to the questions about using water and/or water/alcohol mixtures:

Please see Part 02 of the evaluation. If this does not answer your questions, please repost your question under Part 02.

With regard to the question about grounding the filler rod: Like most modern welding power supplies, the output of the Multiplaz power supply is "floating", that is, it is not electrically connected to ground unless you deliberately do so. Only the metal case of the power supply is connect...
