Thanks. I read both topics. It was enlightening. Formerly, I was under the impression that the voltage selector switch controlled the heat input but it seems that contact-to-weld-distance (stick-out) and wire-feed-speed has, perhaps, the greatest influence on current and, therefore, heat input. ... -
Thanks. I appreciate your tips and advice.Leave a comment:

A pair of 5/16" steel plates were placed 90 degrees apart and welded together for practice. My Hobart 190 doesn't show a recommended voltage/wire feed speed for 0.030" E71T-11 wire so I left it on #4 voltage and 60% wire speed which are settings for 1/8" thick steel.
Both...Last edited by Badbmwbrad; 02-17-2019, 07:51 PM.Leave a comment:

I am not an electrician but my understanding is the electrical service distribution panel has two "hot" bus bars. Each bus bar is at 120 volts AC potential. There is also a neutral bus bar and it's located off to the side of the panel.
A voltmeter having one probe touching either...Last edited by Badbmwbrad; 02-16-2019, 06:53 PM.Leave a comment:

You can purchase adapter extension cords ready made. I purchased an adapter extension cord to connect my Hobart Handler 190 to my portable generator. See attached photograph.
My generator has a 4-wire twist-lock receptacle into which I plug in the extension cord. Note that only three of...Leave a comment:

At Welding Tips and Tricks, Jody recommends stuffing a length of stranded copper wire beneath the work piece ground clamp. These braided ground straps were fashioned with stranded copper conductors I salvaged from the pigtail leads of graphite brushes (motor-generator set brushes).

I love Welding Tips and Tricks! Tack welded right end only.Last edited by Badbmwbrad; 02-11-2019, 09:20 PM.Leave a comment:

Two channels were placed side-by-side. I started on right side with a tack weld then welded from right to left. Weld heat distortion caused misalignment; opening a small gap which I couldn't bridge. I tried making a weld-overlay to narrow the gap then it just melted through.
Maybe I should...Last edited by Badbmwbrad; 02-11-2019, 09:19 PM.Leave a comment:

These little portable generators are equipped with mechanical governors on the engine. The engine's governed speed is 3,600 RPM in order to generate 60 cycles/sec alternating current. There is a slight (but noticeable) time-delay when the generator is loaded (weld-arc initiated) and engine RPM drops...Leave a comment:

I got a new Hobart Handler 190 this past Christmas. It's being powered with a Winco Dyna generator DLC6000E. The generator output is 5500 continuous watts and 6000 surge watts. The generator has a 240 VAC twist-lock receptacle. My extension cord has a corresponding twist-lock plug, 8 gauge conductors...Leave a comment:

I'm attributing my improved vision during a most-recent welding session to eye micro-surgery. The ophthalmologist replaces the eye's natural lens with a clear silicon lens resulting in improved visual acuity, crystal clarity and brilliant colors.
With my welding helmet on and an arc weld...Last edited by Badbmwbrad; 02-15-2019, 08:43 AM.Leave a comment:

Thanks for the encouragement! Hobart 0.030" flux-cored wire E71T-11. #4 voltage setting 60 IPM wire speed.
This was an open butt weld. I clamped the pipe elbow and pipe Tee together with a large-jawed Vice grip; sandwiching a length of stranded copper wire between the jaws and...Leave a comment:

Learning to Use Hobart Handler 190 Mig Welder
My first successful weld isn't pretty but it's functional. This trailer's guard rails are assembled from 3/4" NPT pipes (galvanized). A close nipple un-threaded at one corner. After grinding away the zinc, I stich-welded around the butted pieces. Two stub-outs/bird's nests later... ...
