Chose Well After Plenty Comparative Research
on May 23, 2013
Researched six months to decide on a home-use unit, one providing 'Energy Saver' feature (IGBT), Pulse and AC option over old transformer unit, and not equate three months mortgage.
Additionally, I looked at PowerTig 185 but per data it lacks Pulse feature, and Foot Pedal is not a Standard Option. Considering decent Pedal alone waivers $200 and absence of Pulse feature I chose this.
I inspected unit externally/internally: External appearance, feel, weight, case gauge is one of quality to include switches, knobs, cable connections. Note: Upon cover removal I found stainless steel sheet metal screws (holding green cover at bottom) to have slightly stripped-out internal frame anchor - nutplates should be employed. I used 1-size larger SS screws upon reassembly.
Two decals on rear of unit caught my eye, an "Inspected By" and a "Tested By". These Decals are not placed there for `show'; they shout Management's effort to meet/exceed pre-established quality and reliability Standards. I mention for these decals serve a very familiar old `best practice'.
A brass single-flow Flowmeter is included, and by weight, feel and overall appearance it should perform well. [Is performing well]
Torch is an air-cooled 2-Piece size 26 attached to a 12' heavy rubber-coated lead. Torch has a removable momentary switch for 2T [press to ON, release to OFF] and 4T [press then release to ON, press and release to OFF] control. Both Torch and Switch cables are protected within sheath. Torch package appears/feels tough enough. [is holding up, performing well]
Foot Pedal: I prefer one of lower and wider profile due to my shoe size Clown, less prone to flop on side during use but I'm using it and it works well.
Earth Cable/Clasp appear ample gauge; Consumables Pack provided for Torch includes a basic set of Caps (2), Collets/Holders, Cups (2-ea of different standard size) and note, Tungsten must be purchased separately.
Electrode Stinger, a type I've never used appears to earn good grade. Its clasping feature holds electrode firmly in-place.
Application: New unit has taken me time to adjust - observations:
Gas flow: Has Pre-flow dial 1-10 sec and a Post-flow dial 1-25 sec.
Silky-smooth HF arc start by pedal or digit switch vs scratch...Tungsten grinds now less often and appreciated. [Also has Lift TIG (touch & lift)]
Pulse Settings: Has a three-mode Pulse Frequency switch: positions, Off > Low > High, plus a dial to adjustable Low settings 0.5 - 25Hz pulses per second, and High setting from 25 - 150 pulses per second.
The Pulse Amps current dial allows me to adjust the low amp side of pulse (aka Pulse Amps/Background Amps/Base Amps) to 5-95% of Weld amps.
Pulse Time On/Balance dial: Allows me to lengthen or shorten amount of time the Pulse amps (low amps side of Pulse) stays on per duration, 10% - 90% of each Pulse Frequency.
I've watched its LCD, it's repetitively accurate and its pre/post gas flow timer settings as well. Its cooling fan, to me is quiet enough at a constant hum.
Of note is unit has a 'Down Slope' dial but not an 'Up Slope' dial. This feature paces amount of amps, ramping down/up for seconds chosen while utilizing a torch-mounted switch. Neither feature applies when using pedal. If Up Slope feature is important checkout unit's bigger siblings.
I've near 20 hours and dedicated first 10-hr inning literally trying to 'MAKE IT BREAK', during Amazon's Return window, via multiple application/setting etc - no cigar.
As many weaned on Blue & Red eyeballing these Green units researching, deciphering/validating opinion of popular units available, I'm content thinking I chose well.
In short: I graded on Comparative Merit and find unit gifts good-looks, features, quality and performance at a price unmatched period.
UPDATE Dec 2013: No issues and boss let me acquire new torches, Superflex leads with DINSE & 9mm gas QD adapters and I remain impressed with unit's performance.
Also I note Everlast has a newer 200DX Owner's Manual on their website. It's an improved, edited, illustrated manual than initially received, and explains unit's prime features nearer application level.
Update Oct 2014: Welder continues to perform as it did out-of-the box, now well over 100 hours (home use).
Details mating Superflex lead: I used DINSE Adapter P/N "CK SL2-35QD" (1/2"(35)) post twist-lock with 9mm gas QD (for Everlast units) for size 9 and 17 torches per site - purchased through Weldfabulous website.
*Note smaller Everlast units (below 200-amp) accept a smaller DINSE Adapter*
If needing a 7-pin connector (cannon plug) for cable end to add pedal or torch-mounted switch, search "Waterproof Rubber Cover 7-Pin Cable Connector P7D" here/elsewhere.
