MedWeld 200 Series Resistance Weld Controls

A Low Cost Control With Top-of-the-Line Capabilities

• Weld sequence data changes simply by scrolling up or down
• Weld sequence, voltage, current, pilot input status and more, clearly visible at a glance
• Compact, modular design simplifies maintenance, saves floor space, and reduces spare parts inventory
• Up to 50 different weld sequences
• Linear Stepper programs assigned to each Pilot Input increase tip life
• Complete diagnostics to include error messages and fault output
• Unique operational parameters for providing automatic adjustment and notification of the weld process:

• Automatic REWELD for low current conditions
• Dual valve outputs for independent or 2-stage gun cylinder operation

With a single function key you gain access to all screens. The silk screen and display clearly define the fixed weld sequence, allowing quick and easy data entry. From one single screen you can view the weld sequence and status information to include:

Pilot Inputs 1 and 2 status Weld/No-Weld Status Actual Line Voltage Low Voltage During Weld

Secondary Weld Current Power Factor Total Weld Count % Current Boost Fault Code Marquee

Multiple Weld Schedules

Up to 50 different weld schedules may be defined to handle multi-thickness metal stack-ups or varied surface coatings and steels. These sequences may be chained together in pairs to build a more complex weld program, or they may be set up in successive order to form a pattern for a repetitive production process.

Application Flexibility

Select between Standard Initiation (with 2 separate pilot inputs assigned to independent gun valves) or Seam Welding operation. A second stage input is available for palm-switch initiation of a fixture or a 2-stage foot pedal equipped with an OHMA cylinder requiring multiple valves.
