STA-100A Single Phase AC Resistance Weld Control

• Consumer Appliances
• Nut and Stud Welding
• Electronic and Automotive Components
• Aircraft
• Office Furniture

The STA-100A utilizes a unique combination of an LCD screen and separate keypad, eliminating the need to memorize special codes or follow LED indicators. The screen’s simple, intuitive design has been configured to enable viewing of programmed
and monitored weld data and allow the user to quickly and easily make modifications.

Miyachi is proud to introduce the first in its new family of AC resistance weld controls. STA-100A is the most advanced, yet simplest single contactor unit on the market. STA-100A features an intuitive, easy-to-use programming screen and is designed to control and integrate press welders, seam welders, robotic systems, rocker arm welders, and special machines.
 

Features & Benefits

Simple, intuitive programming screens
The STA-100A utilizes a unique combination of an LCD screen and separate keypad, eliminating the need to memorize special codes or follow LED indicators. The screen’s simple, intuitive design has been configured to enable viewing of programmed and monitored weld data and allow the user to quickly and easily make modifications.

Programmable upslope/downslope
Program upslope and downslope on both Weld 1 and Weld 2 and control how quickly current is passed through the workpieces. Ensures precise control over the welding process and success in metals joining applications including “hard to weld” materials.

Unique linking feature
Weld schedules can be programmed more efficiently. Minimizes more complicated PLC programming! The STA-100A AC
resistance weld control is the only control capable of linking chaining, successive, spot, and seam modes.

Current Stepping
Automatically steps current to compensate for electrode wear ensuring better, more consistent welds.

Versatile cabinet design
A removable door makes it easy to hardwire and gain access to internal connector strips. The cabinet can be mounted either forward facing or 90° to front without the use of special brackets or tools, ensuring the end-user greater flexibility and ease of use.
