Other types of welders, like Arc ? Answered

I have an Arc Welder. Will your classes have much to do with this type, or mostly just for MIG welding devices?

I think my problems begin with matching power selections, and the gauge of metals I'm welding.

I also wonder about different types of welding rods.

I also, obviously want to get an instant darkening welding mask, because I can't see a thing until my rod makes contact with the metal and lights up with the spark.

This class is geared towards MIG welding because it is what most educational institutions use to teach welding. In the future perhaps we can put our heads together at Instructables HQ and build out an arc welding curriculum.

I suggest checking out some forums like weldingweb.com or www.millerwelds.com/resources/communities/mboard. They have a lot of great information from experienced welders of all types. That's where I picked up most of my knowledge for arc welding.

Arc is all I care to know. I'm not great at it, but I'm getting better with experience :)

MIG welders are mostly just point-and-shoot where as arc welders take a bit more technique (angles, speeds etc.) but it is rewarding as you can do a ton of stuff with an arc welder like cut metal and drill holes. The best way to learn to weld is to have an experienced welder teach you in person, see if your local technical school teaches a short welding class.

the amperage is generally are determined by the thickness of the rod and metal but also by the type of rod.

The rod numbers (7018, 6011) are the sticks' characteristics the first two digits are the tensile strength of the rod, the third digit is in what positions can you use the rod (overhead, flat, etc.) the last digit is the polarity of the rod. So a 7018 rod would have a tensile strength of 70,000, be able to be welded in all positions and can be welded with AC, DC- and DC+

Also buying an auto darkening helmet is an extremely good investment and remember to always wear proper PPE when welding! Good luck!
