Craftsman 180 welder

Picked up this welder at an auction. It has the plugin leads with choice of A(red) and B(green) for one of the plugins and color coded numbers for the other. So my question is which lead plugs into A and B, the one that holds the welding stick or the one that is tied to the piece that is to be welded?
 
It depends if you want to weld straight or reverse. The best thing is to turn it on an take a meter to it then mark + - on the face of the machine. Straight electrode neg Reverse electrode Pos. Different rods will dictate that.
 
Most likely an AC only machine so it won't make any difference which way the leads are connected. If it has DC, it will say + and - and also be listed as DC on the nameplate.
 
I think that is an AC only welder as my dad has a 200 amp Craftsman welder that he bought new in 1951. The 'A and B' is for the high and low heat ranges and I thought connected to the ground/work clamp and the rod holder lead goes to the sockets with the amperage numbers marked by them.

Been so long since we put leads on it that I may have it backward. Weldors- would it make a difference on an AC only machine.

It depends on how you want to weld. if you want DC welding you put the cables on the right side of the welder. You then have 180 AMPs DC.

If you want more AMPs you plug it into the left side. There you have 240 APMs ac.

Then you fine tune the amperage with the crank in the top.

These welders have a pretty low duty cycle when in the higher amperage ranges.

You can down load a owners manual on line. You will just need the exact model number to get it.
