Gesswein exclusive for the mold and die industry!
Developed for Mold & Die repair: the PUK POWER U4. Precision welding made easy. Made in Germany.
Incorporating the latest technology, the PUK U4 POWER offers an easy to use solution for precision mold and die repairs. Utilizing micro TIG technology, the welder produces small, consistent spot welds that penetrate the mold surface. The welded areas are strong and can withstand the pressures and working conditions during the molding process. All heat is concentrated at the spot of the weld thereby eliminating the possibility of distortion and metal stress caused by overheating.
Repairing parting lines, mold seams, and three point corners and edges
Filling in pores and deep scratches on the mold surface
Weld into slots, corners and ribs
Repair slides, ejectors, and core pins
For use on all common tool steels, stainless steels, aluminum and copper
The system comes complete with:
The PUK U4 POWER Advantage
Save money: Keep mold repairs in house! Stop sending out for laser and precision welding. Affordable alternative to a laser welder at a fraction of the cost.
Save Time: Repair your molds the same day. No pre-welding heat treatment required. Welds quickly: 1 spot weld every 0.8 seconds! Small spot welds polish out quickly.
Easy to use: Ready to use with pre-programmed presets for most common applications. Takes the calculations and guess work out. Extremely accurate weld placement. Sharp electrode tip (0.6mm) touches the exact location of weld spot.
Mobility: Take the U4 welder to the press for repair! Magnetic microscope attaches directly to mold while still in the press!
Minimal heat: Prevents damage caused by overheating of mold, thus increasing life of the tool. All heat is concentrated only at the spot of the weld.
Pre-Programmed and Ready To Use...
for Steel, Aluminum and Copper.
Take the guess work out! Simply select the pre-program for your mold repair application and start welding! Each pre-program is set to the optimal weld pulse and time lapse for the specified mold repair application. Or if you prefer, manually override the pre-programmed settings to dial in your preferred setting.
Weld anywhere on any type of mold large OR small! The adjustable and magnetic microscope base affixes to any metal surface. The microscope arm is extremely flexible to allow for comfortable welding on almost any mold surface. Keep the microscope at your bench or take it to the mold for a quick in-press repair. The 10X microscope comes complete with integrated LED lighting for proper illumination of the welding surface. A protective eye shutter built into the microscope provides protection for eyes. Field of view 20mm.
"We have used it three times now and it has already paid for itself! It is very easy to learn to use; all my guys are using it. Even the ones who cannot use traditional TIG welding gear. The PUK is a VERY useful tool to any mold shop."
- William Barnhart, Tool Room Supervisor at North American Lighting
"With the PUK U4 we have enhanced our in house welding capabilities by filling a gap between micro welding and laser welding. It has also put some micro welding capabilities in the hands of many of our moldmakers that have little or no welding experience due to the ease of use and small learning curve. I really like how the PUK U4 does not introduce the amount of heat into the part that conventional TIG welding process does. This results in little or no sinking around the weld, making our repairs nearly invisible. We use the PUK U4 for welding parting lines, scratches, filling in small voids, etc... The PUK U4 has paid for itself in no time at all because of our ability to greatly reduce the turn-around of getting an injection mold back into production."
- Mike Sekulski, Seitz LLC.
"We've added the PUK U4 welder to our mold repair department and are very pleased with the results. Typically in the past we would have to send out all small detailed welding to be laser welded. The PUK U4 has allowed us to keep some of the small touch ups in house. This has allowed quicker turn around and less cost as we do not have to ship off site. We have experimented with several different base materials and have had good success with the weld for minimal sink and color match. The main materials we have tested on are: P-20, 15-5 stainless, Mold Max (copper)."
