Which Welder.

For a all around welding machine, I would consider
a CC, CV as a minium. That way you can add what ever you want at a latter time, GMAW, GTAW, SMAW,?.

You can always add a scratch start Tig torch at any time. You don't need HF or gas solenoid valves nor wet torch. The Tig hot lead just clamps between the rod holder jaws, for current flow. The gas on/off flow is controled buy a sliding gas valve on the torch handle and you will need a flow meter. I welded a many miles with this set-up.

Thin sheet metal can also be welded with a oxy/act torch. Works very well with a small tip and stress releives the metal as you weld which is what most tractor SM needs because of the viberation. You can also weld thick plate with the same results.

You also might want to do a search on this website and see whats been talked about on welding. Alot of good info from experience is posted!

Good luck with your schooling and most of all have fun!

The best route to go I think would be to go on and buy you a good quality stick welder but be sure it has AC and DC capability and a fine adjustment if possible. Later on you can buy just a TIG torch and get a gas bottle and regulator and TIG off the same machine using DC. You won't have near the control of a fancy TIG machine with a remote but you can get a lot done with a little practice.

I currently use a similar set up that I run off my portable unit. Since I already had Argon on my rig for running Aluminum wire through a spool gun (MIG), it was very easy and inexpensive to add a TIG torch. I found a complete torch assembly at a tool autcion for $12.50 and just clip it to the stick weld stinger and the hook up to the gas outlet for the MIG, and vilola, instant TIG.

I currently have my portable all rigged out on a tandem trailer and can travel any where and do just about anything with most any metal. I also carry a large chop saw, air compressor and 3/4" capacity Plasma cutter besides the oxy / accetylene torch to handle cutting chores. My little rig makes most any job possible whether it sitting in a shop or broke down on the roadside.
