My first welds with my PA 160 STH

[ironmanjay]

This is my first welds ever with a consistent arc and only my 3rd or 4th time welding. I user 6011, 6013, and 7018ac rods all at 95 amps.

Need to know the Dia. of the rods,,,95 Amps can be too hot or too cold depending on the Dia. and the Rod Type.

[ironmanjay]

6011 was 1/8, 6013 and 7018 3/32

Little hot for 7018/6013. Only need about 80-85 amps MAX. I can do it with 70 or so usually without an issue.

Well okay now that we have the Dia,s Time to read the welding specs for the rod's,,,these are available from hobart at their web site,,they will tell you the amp ranges and the arc gap distance for each,,,good reading and really helps in laying beads...good luck with your new welder..

Ok the issue I was having with my 7018ac rods on my 160sth was the rod! Last night I used some 7018 1/8 rods @125amps on a TIG 200 and they were porosity free. We ran my 7018ac rods and they were loaded with porosity. The mess in the middle was 6010.

Time to cook the 7018ac to see if you can restore them,,,7018 is easily affected by moisture..at least you have figured out the problem,,a lesson well learned is a lesson you will remember..before they invented memory pills,,,mom just used to give us boys a slap,,,improved our memories dramatically,,,

Dad did our memory/reset at our place. We laughed when Mom did it. ONCE!

I had bought a bunch of 7018 rod from Lowes and was very displeased with the welds, buco pin holes. I then discovered it was 7018 AC. It's crap in dc mode and chucked it all out.

If you were getting pin holes, it was probably too long of an arc length. I've used 7018AC's successfully in DC many times. It will work in AC or DC. They just add something extra in the flux to run really stable
on AC.
