Smash operational bottlenecks: concentrated heat reduces solder time many times over. Improve solder joint quality: poor solder joints are often the result of insufficient heat throughout the joint, creating weak spots. Eliminate thermal damage: traditional soldering methods introduce too much heat into surrounding areas damaging critical components or desoldering of previously soldered joints. Reduce liability: light-weight hand pieces cool within seconds greatly reducing likelihood of repetitive strain injury and virtually eliminating the burn risk for the user. Solder in tight spots: versatile systems allow easy access to restricted areas. Cut down on energy consumption - instant heat means you're not paying to heat a soldering station all day long. Save on maintenance and consumables: electrodes last twice as long as soldering tips and don't require constant rewetting. Users of this product have stated that they use it for several jobs which include but are not limited to: reflowing solder on PC board leads, repairing and soldering model trains. This system consists of a model 105B2 (1100 watt) power unit, a model 10513A panel attachment and a model 10519 footswitch. This System can be used to create accurate, trustworthy solder joints in high volume, production applications. It allows for more hands-free operations and is used very extensively in automotive parts rebuilding and salvage operations. Uses include but are not limited to, soldering bus bars, lugs starter and alternator leads, battery cables and similar electrical work. 1100 watts. 1/2" Electrode size. Tapered pins connection type.
