PRAXAIR'S PROSTAR™ WELDING WIRE DELIVERS RELIABLE, PREDICTIVE PERFORMANCE WELD AFTER WELD. ProStar “twist-free” mild steel welding wire is the right choice for consistent, high-quality welds, throughput, and quality for automated welding processes. With no cast or helix, users can avoid uneven wear on consumables—typical with standard welding wires—which can cause arc wander, over-welding, feed issues, and shut-downs. |

feed systems
Advance Your Wire's Delivery
PRAXAIR FEED SYSTEMS FOR FERROUS AND NON-FERROUS MATERIALS, INCLUDING TUBULAR WIRES.
Four reasons why you should equip your automated welding system with ProStar™ Conduit.
|
1. Reduce Burn-Backs ProStar conduits reduce pull tension issues that are associated with weld wire burn-backs at the contact tip. |
 |
|
2. Reduce Weld-Necking ProStar conduits minimize uneven pull tension between the resting state and slack consumption, which is the cause of weld necking just after the weld starts. |
 |
|
3. Reduce Over-Welding ProStar conduits reduce pull tension to help improve your weld accuracy and precision, further decreasing the need to over-weld. |
 |
|
4. Facilitate Wire Farms For high productivity weld cells and multiple shifts per day, a wire farm that incorporates ProStar wire and Praxair's 24/7 feed system can eliminate wire changeouts and downtime. |

24/7 Systems
ProStar™ 24/7 System
| ELIMINATE CELL DOWNTIME WITH CONTNUOUS DELIVERY OF WELDING WIRE TO THE ROBOTIC CELL.
Eliminate downtime caused by manual wire changeouts. Praxair’s 24/7 wire feed system helps improve and protect the productivity of your robotic MIG welding cells. Each “wire farm” consists of two 1,200 lb drums of ProStar wire, the 24/7 system swing arm and stand, RW 24/7 butt welder, and 24/7 die. Praxair’s 24/7 feed system is designed to serve a robotic cell sequentially from two wire drums — enabling continuous delivery of welding wire and avoiding downtime. |

ProStar 24/7 System Components
| 24/7 Butt Welder
Joins mild steel wires of various diameters. Set the welding current to Position One for .030 to .062 diameter wires. Select Position Two to weld 5/32 diameter wire. |
 |
|
24/7 Die Set With shaving plates available for many wire diameters, the 24/7 die set ensures a consistent diameter across the welded seams when drums are joined together by removing the resultant flash and any burrs from the welding process. |
 |
|
24/7 Swing Arm Prior to the first drum being spent, its wire end is welded to wire start in the full drum. As the wire source transitions from drum to drum, the swing arm simultaneously rotates to supply wire from the full drum. |
