Word from the Wizard - April

A manufacturer of attachments for heavy construction equipment was not happy with the performance and durability of their current MIG welding guns. Their heavy duty application required a heavy duty MIG gun that could withstand high heat and high duty cycle welds with large diameter cored wire. The poor cooling of their current MIG guns caused them to be too hot for the operator to handle and also resulted in premature failure of welding consumables. Frustrated with the ongoing performance issues, they decided to trial PowerBall® 500 Amp MIG guns that feature patented technology with superior conductivity and cooling. Welders quickly noticed less heat build-up in the handle , improved welding quality and a significant increase in consumable life . After a successful trial, they are now in the process of...

Word from the Wizard - March

A mining equipment manufacturer utilizing a large robotic tower system on a linear track recently reached out to the Wire Wizard Team to optimize their wire delivery setup. The system had a drum of bulk wire located on a platform attached to the tower, which made wire changeout difficult and unsafe for team members responsible for running the wire. The Wire Wizard Engineering Team worked with the facility to develop a solution to move the drum to a safer and more accessible location, as well as reduce friction on the wire through a long run to the feeder (approx. 100 ft). Wire Guide Modules and Extra Flexible Conduit were utilized to relocate the drum from the tower platform to the flo...
