Solution Model

Resistance Welding Controller

Repeatability The Unitrol Solution® uses the most advanced digital electronics available – your guarantee of absolute timing accuracy and consistent heat control. It lets you set your machine and be confident of an accurate weld without the worry of constant adjusting, tweaking and fiddling associated with older type controls. Uniform, predictable, consistent welds repeated over and over again – that’s what the Unitrol Solution® is all about.

Reliability The Unitrol Solution® is designed and built for continuous trouble-free production. Every unit is tested on a production welder before shipment to guarantee effectiveness of the high quality components utilized in each control. All functions have built-in trouble shooting indicators that save you valuable time and hours of guesswork.
