Four sensors · knobs rather than buttons
Hobart 770890
Four arc sensors and three analog knobs, from a maker that publishes its viewing area as a single number nobody can square.
Four arc sensors and three knobs. That is the proposition, and for a workshop it is a better one than it sounds: sensitivity, shade and delay on analog dials can be changed with a gauntlet on, by feel, mid-job — where a digital panel means taking the glove off and looking at a screen you cannot see through the visor.
The sensor count is the specification that matters alongside it. Four is what lets a cartridge see the arc when the work, the torch or your own hand is in the way, and on this shelf only the ESAB, the Digital Elite and the larger YESWELDER match it. The grind switch and the auto-on at arc strike are the ordinary conveniences, done properly.
Where the page falls down is the two numbers it half-gives. The viewing area is “9.3” widescreen”, which is one dimension with an inch mark where an area needs two — and on a shelf where the ESAB publishes 4.65 by 2.80 in and both YESWELDERs publish their width and height, that is the one figure a buyer would compare. And the listing calls the helmet 77890 twice, dropping a digit from its own model number. The optical class and the switching time, which this shelf’s buying tip asks for first, do not appear at all.
