So I started a thread over and ADV Rider (found here: http://advrider.com/index.php?threads/alphatig-200x-review.1041922/page-3 ) about my Alphatig, and another fellow there ended up buying one as well. He gave me permission to share his thoughts and pics of his welder here, so here you go!
Without any further ado, here's what vintagespeed has to say.
So i've had my AlphaTig 200 for a few weeks. the shipping from Amazon
was super impressive, i ordered it on a Wed mid day and it arrived at my
door for free on Friday. how's that for service? it was well packed
and arrived unscathed.
the machine is good looking, has lots of bells & whistles and weighs
about 40lbs, much lighter than my MIG. i bought a 120cu/ft bottle of
Argon and some 2% Lath sacrificial tungstens and some filler; 4043 1/16
if you're considering this machine, dont even power it up until you have
a 240v circuit for it. it's seriously not worth the time to try to use
it on a 120v service line, it works but it's not happy. when i finally
pulled my 240v and ran it for the first time on 240v it was literally
night & day difference, the pedal was more responsive, the arc was
cleaner and the machine hummed along quietly even at high amperage.
just beautiful compared to the noisy and raspy way it ran on 120v.
when i first got it i did some DC to get familiar with it and was fairly
successful so i switched over to AC and spent many agonizing days
questioning my sanity for trying to learn something new....but then i
did something that opened my eyes. i switched it back to DC and tried
to run a bead with it and hated every minute of it! i jumped back to AC
and never looked back, welding aluminum is awesome! it's clean, quiet,
and enjoyable. this machine really does weld nicely on aluminum, every
review i read said the same and they were right.
i've used all the features of the machine and i most like just running
off the pedal, but pulse is really great if you turn it up insanely high
speed and just feed it filler. it's almost like cheating. i need to
spend more time on pulse and try to really tune it in, if i was doing
some kind of repetitive task it would be wonderful for that.
i'll post some pics after i make a new batch of coupons to stick
together. last night i was just running some beads at 175amps on 3/16
aluminum plate and the machine was quietly humming along at 170hz laying
nice pretty, shiny beads.
i'm stoked on it and will report back with some pics and any issues that
arise. i'm almost ran out of argon so i'll pick up a fresh bottle next
week and keep buzzing away. so far so good!
