I have finished grinding the bevel and I am now ready to heat treat. This blade is made from a castoff hoof rasp. Dose anyone have any idea if they are air, water, or oil cooled. Any suggestions would be greatly appreciated. Thank you

As a certified professional welder, this is how I view you dilemma(s)
With a single vee bevel, I can run a good but joint @ about 90 amps, in all positions, 7018-1/8" rod. This is using a 1/8" 6010 rod a lower amps (don't really remember the setting) root pass. This is on 3/8" ANSI A- 500 (A-36) Plate, with and w/o a backup plate.Leave a 1/16" land on the bevel and also use a 1/8" root gap. What I am trying to say is that I do not think that your machine is to small.
With respect to the slag inclusion, it sounds like you angle of attack is incorrect. Use a lead angle of about 10 degrees while holding the stinger and rod at about 45 degrees with respect to the work. This is what I do. Also make sure that your arc length is correct. With a 1/8" rod your arc length should be about 1/8" ( if I remember correctly)
Take all of this information with a grain of salt, I have not used SMAW (aka stick) for about 5 years.
I had a hard time with stick in school, but I felt a great sense of accomplishment once I got it. My suggestion like other would be to stick with it. You can do a great many things with stick, and due to the low amount of consumables required to stick weld as compared with GMAW (MIG). I have a MIG machine I like it it was expensive and I will take me a lot of projects to equalize my ROI (rate of return). All told I spent $1,000 on the machine and consumables. Another $500 on a torch and bottles. -
So, sounds like I could use it but it is not preffered due to smoke starts, and lots of clinkers and no coke. It also appears that I could just as easily use Hardwood charcoal and get better results for less aggravation. I will let you all know how things turn-out.
Thank you to all who have replied

I am new to the forum, I have been a certified professional welder for the past ten years, but my smithing knowledge is religated to heating square stock with an O/A rig and twisting it.
My question is this, what would happen if I used Anthricyte Coal in place of Bit. Would this work for use in the forging process. My project is to manufacture some mortise chisels of various sizes. Would this type of coal leave any pit marks or any other impurities that I am not aware of? Any help would be greatfully received.
Thanks,

Thank you chuck I will give it a test on the remainder of the file. I am assuming by brine you mean a mixture of salt, soda, and water.
