I'll jump in here and say that I think your amperage is pretty close, or within 5 amps to the hot. I usually run 3/32 7018 at about 85 amps, I also almost always run a 6011 root pass for the joint you pictured. I've found over the last 17 years that I've been welding, by no means am I claiming to be...

Nice link, thanks!

That 312-16 rod is fine, but you may find easier welding with 308lsi, especially on older (read used and abused) materials. There isn't an engineer on site who knows the alloy your welding on? I would suspect a 300- series. 316 has a higher corrosion resistance than 304, particularly for salts and ...

Vertical stainless is one place I think a remote amp control belongs in stick-welding, because you're right. When your amps are set for a good start, you get a good quality inch or so, then the heat-soak causes sagging, and even drip-out. When your amps are set for a good run, you get a cold start ...

Hello, Brand new to the site, but I've been a journeyman Millwright fro 17 years. In the foundry where I work I from time to time have to do some welding/repair on 1/4" to 1/2" Stainless plate. We generally use 1/8" 312-16 Crown Alloy rod, running 105 amps or so DC-RP. Any tricks to ...
