I want to power my Lincoln 225 stick welder (240V NEMA 6-50 plug) with a portable generator (240V 6-30 receptacle). Could you explain how to wire a jumper for that? I know I'll be limited to lower welding settings but never use over 105 anyway.

Black and white of the cord to the Hot terminals of the receptacle and cord cap, Green to the box and ground terminals of the recep. and cord cap.

Techy's adapter cord is a good solution. An alternative would be to get a dryer cord with a 6-30 plug and install it on the welder, replacing the existing cord. If you never use the higher current settings and will usually use it with the generator, this might be a neater solution.
