The Unitrol Solution


The Unitrol Solution® uses advanced digital electronics – 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.


The Unitrol Solution® lets you say goodbye to inaccurate hard-to-understand, out-dated controls that put limitations on your existing equipment. It’s accurate, simple, and gives you the ability to do more with your equipment than any other control in the market! It also includes all RWMA functions in each individual program (slope, pulsation, forge delay, etc.) – at no extra charge.


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.


Other controls, old and new, are made with far too many components which increase the likelihood of breakdown. The Unitrol Solution®’s concise and uncomplicated design assures continuous production from your welder. Should a problem ever occur, the Solution®’s self-diagnosing feature, together with only two circuit boards, lets your plant personnel bring the welder back on line in minutes. No wiring to deal with – just plug in and start welding.

Available Options

The Unitrol Solution® offers options to maintain quality and safety:

  • Soft Touch Safety System
  • Tip Force Monitoring
  • Constant Weld Current
  • Electronic Pressure Regulator System
  • Printer/Communication Port


Soft Touch Safety System

protects operators against pinch point injuries. (requires purchase of Soft Touch hardware)

Microcomputer Control System

offers ultimate flexibility with minimum components.

Factory Programmed Software

to handle all welding functions – now and in the future.

75 Weld Schedule Memory

Electronic Counter

automatically displays welds made or completed parts welded.

Water Saver Circuit

to drive 115 volt solenoid valve, conserve water and protect operator during tip replacement.

Tip Pressure Calculation

automatically calculates required pressure regulator setting for desired tip force.

Dual Level Initiation:

Level A closes tips, Level B starts weld.

Anti-Tie Down

for double hand button use. Automatic detection for foot or hand switch operation.

Dual Schedule:

Assign any two of the 75 welding programs to two different initiation inputs.

Positive or Negative First Half Cycle Firing,

keypad selectable.

Half or Full Cycle Count,

keypad selectable.

Electronic Memory,

no battery required. Retains all data for an unlimited time. Returns to last used program after power is turned on.

Intensifier Valve Control

for air-over-oil or intensifier cylinders.
