hello all i read through this post with interest and wondered what welding tool i would have if i were only allowed one , that would be oxy/accetlyne for all round adaptability you can solder soft/hard braze bronze weld light the fire quick weld cast iron pre heat stuff cut gouge all manner of material , second would be a big welding transformer i could add a rectifier, high frequency generator , remote wire feed those are the base welding tools and of course the fire . in the uk the insurance people freak out at accetlyne but you might have better over there . whatever you chose or are able to get it will be fine you have just got to put the hours in to develop the skills. and keep the rods dry dry dry !!! good luck .
