Hello, I teach high school and college welding and I am offering my advice from many years of floundering and mistakes. Take it or leave it.
1) Textbook- after using 5 different texts, including modern welding, hobart and others, there is only one true comprehensive welding text; Welding principles and applications by larry jeffus ( a welder)
2) Curriculum- AWS Entry Level welder program. It gives you an industry standard complete competency based curriculum to drive your program.
contact D. Hevia at AWS. My advisory council truly beleive in this program and hire students with this certification because they know the student has mastered the competencies in SMAW,GMAW-s,GMAW spray arc,FCAW,FCAW-g,GTAW (alum,mild steel, stainless), OFC, CAC as well as symbols, and safety.
3) Get your CWE or CWI, the education you learn in jumping through that hoop are irreplaceable in the classroom.
4) Dont get buy high tech equipment. Most arc welders are capable of doing what you need, just make sure they have acceptable duty cycles. We have some lincoln arc welders that are 20+ years old and do everything a new one will.
You can short circuit,run flux core and spray arc with the 255 machines with .035 and 92/8 gas just fine no matter how much technology a salesman tries to sell you. www.lincolnelectric.com
For tig we use the lincoln 175 squarewave pro its also a great little arc welder and is all the tig you will ever need for alum,stainless,and mild steel and is the least expensive!!
You dont need pulse
You dont need high tech wire (metal core etc...)
5) Make the suppliers give you bids on the supplies you think you will need for that year. Tell them you want a locked in price, if they say they cant thats b.s. they can. Never be afraid to "dicker or jew" for a cheaper price. My suppliers know when I walk in the door not to shoot me list price, you would be shocked at thier markup, ESPECIALLY ON GASSES AND BOTTLE RENTAL.
6) Put together an advisory council with as many people as you can think of. Meet once a semester, buy them supper or breakfast and make thier time worth while. Ours meets tomorrow and I look forward to it!
7) Good luck !!!! If I can help you feel free to email me.
Sincerely, Don
