[QUOTE=evil herbavore]I'm a newbie to welding....so let me ask the simple stuff;
oops -deleted the questions...oh well,answers:
common for production welding to be done on a steel table, ground cable terminates in a lug that is bolted to the table, no clamp used, metal table to metal workpiece contact is sufficient.
the cleaner, the better....there are times ,such as the vette frame, where removal of rust between the parts is not feasible, thats when 6xxx stick is best

flux core wire is made to be used without gas...i've never seen it written up as a ''qualified'' welding procedure using both...outdoors the shield gas is carried away too fast to be of any benefit...indoors the gas shield produces stronger welds and requires only spatter removal (if desired) prior to painting or other cosmetics,multi-pass welding can be done without flux chipping time/effort on thick plates using gas

The wire feed box is a lincon weld pack 100. Maybe I should check the wire. I thought it was flux core but maybe thats the problem. The weld looked so bad to me with the box at full strength I abandoned it for the stick welder. I appreciate all the advice. i burned up a 2 # bag of 6013. Another question, could I have brased the seam instead?

For a normal hand held gun you need the mix of Carbon Dioxide to get the weld to flow out. Here we use 85/15 CO2

You never answered me before about if the welding is on the flat. If so a 7024 would really run better then anything else.
You can not get 7034 anymore but that 3 makes it a real flowing rod.
Flux core digs like stick so stay away from it.

Thanks for all the help and advice folks.

The first two numbers is tensile strength
The next number is position. 1 being all position, 2 flat or fillet only and 3 flat only and the last number is a flux number. The flux gives the characteristics of the rod.
