KÖCO Compact Stud Welding Equipment - ELOTOP
All models of the ELOTOP compact stud welding equipment series are laid out for top performance as well as highly cost-effective drawnarc stud welding. Through their special features they are designed for rough wear on building sites and continuous operation.
High performance, current regulation and microprocessor control ensure optimum welding results even during mains fluctuation, variation in temperature and long cables.
Digital setting of all parameters guarantees precisely repeatable weldings. 20 storage spaces allow to file individual settings. The intelligent self-diagnosis system increases productivity through minimizing machine downtime.
