For It's Size, It's Got Guts!
August 3, 2015
Been using this machine on 240V 30A, and it is glorious. According to the Duty Cycle Chart on 230V I've got roughly 60% duty @ 120A and 50% duty on 130A; this is way more than enough for projects in the backyard. The machine loves 1/8 7018 and 5/32 6011. Miller also claims that it has auto arc force adjustment which I can't really tell by the Volt Amp Curve they provided. But after the first inch of weld or so I am able to jam the rod into the work and the arc won't snuff out. For its size, you can't beat it the quality. Beautiful, forceful and stable arc.
Pros-Hot Start!!! (Only after you've scratch started once to get the machine to return to its 90V OCV, after that easy starts).
- @240V 30A, roughly 60% duty @ 120A and 50% duty at 130A is more than enough for what I do with 1/8 7018, 5/32 6011 and everything under.
-Transit Box is perfect for protecting this investment. There's room for the machine, cables and then some.
- Lenco style stinger and ground clamp are very sturdy. Pretty heavy duty for something as small as the 150S.
-MVP adapter make switching between 230V 50A and 115V not a thing.
Cons-Will not run 6010 properly ,but coming from a machine this small, it's not a surprise and 6011's get the job done for almost anything anyways. For 6010's you much hold a very close arc and no whip, otherwise arc will snuff out.
-Although it has the MVP plugs for 230V 50A and 115V 15A or 20A I wish it had one for 230V 30A (the 4 prong dryer plug) which is what I'm using. I needed to build an adapter so I could plug into my dryer outlet. Not a big deal but maybe in future models they will have this added accessory seeing alot more people have dryer plugs compared to 230V 50A welding and plasma cutting outlets.
-Hot Start is amazing when the machine has been running for a bit, but coming off of idle it should be noted that the 1st strike will be cold because the Maxstar will have dropped it's OCV from 90V to 12V-16V after idling for a bit. At first I though the hot start was not working but came to soon realize that the machine has a voltage sense for safety. Just should be noted so operators know.
