Adding Open Circuit Voltage to a machine so that it will run 6010 has a cost. To see if a machine will run 6010 just look up the OCV. If it's around the upper 70's or higher it will be fine. Many or most are built with price in mind. I'm not a big 6010 fan but i'd still want my machine to be able to run it.

When Miller was questioned as to why the arc didn't stay lit on the inverter based Maxstar 150s that I owned when attempting scratch tig, they said the computer saw an arc voltage that was out of range for stick welding, so the arc shuts off.

That machine didn't have a stick/tig switch. It is different than the 150stl.

It also would lose the arc with 6010 unless held super close. My theory is that the computer again saw a voltage out of its set range.

Just one possible interpretation of the reasons

Scratch start tig should have worked on the Maxstar. It's all there was in the beginning of the small machines. We even used to put scratch start tig set ups on the old 115v Lincoln SP100 mig units. Not pretty and you couldn't turn it down for thin stuff but they worked well for 3/32" steel and stainless. Talking Early 90's.

You are correct, it's the only DC machine I've ever used that wouldn't do it.

But, when it's programmed to shut off in the tig welding voltage range, it's not a very good chance of working.

Miller agreed that it was made that way.

My opinion is they did it so folks would have to spend the extra to get the 150stl instead of the base model 150s.

All the top tier manufacturers target a segment of the market when they design a machine for each price level. Some of their assumptions and decisions won't fit every user. ( such as "most users of E6010 are running engine drives and not 120 volt capable inverters".)
