To officially answer the post:

We have WP 9's with flex heads. These are small as they come, and are limited to 125 amps roughly for duty cycle. These are ready to go with the correct ends, and fittings, and are much more economical to buy than buying parts and pieces, and include the remote switch with the correct end on it...Something Arc Zone hasn't gotten yet. The 9 torch is GOOD quality. Might not be CK level yet, but it is decent enough to last, and weld with, provided you do not melt it down due to over heating it. Price is 129.00 plus shipping for a 15ft. 139.00 for 25 ft.
