100 KVA Acme Press-Type Spot Welder

Model: PT1S-30-100 | S/N 11059 | Weltronic MCS 2009 Digital Control

Overview

The Acme PT1S-30-100 is an industrial-grade, vertical-action press welder designed for high-tonnage precision. This specific unit features a significant technology upgrade: the Weltronic MCS 2009 microprocessor control. While the 100 KVA Acme transformer provides the massive raw power needed for heavy-gauge sheet metal and structural components, the MCS 2009 allows for surgical precision in weld timing and current delivery.

Unlike older rocker-arm units, this press-type welder ensures the electrodes meet in a perfectly parallel vertical motion. This minimizes part deflection, reduces "expulsion" (spatter), and creates high-integrity welds that meet rigorous industrial standards.

Technology Feature: Weltronic MCS 2009 Control

The inclusion of the MCS 2009 controller transforms this machine from a manual workhorse into a modern production asset:

• Microprocessor Precision: Full digital control over Squeeze, Weld, Hold, and Off times.
• Constant Current Capability: Compensates for line voltage fluctuations to ensure every weld is identical.
• Job Memory: Store and recall specific weld schedules for different material thicknesses, drastically reducing setup time.
• Error Diagnostics: Real-time monitoring of weld cycles to ensure process consistency.

Factory Specifications & Technical Data

Key Features & Dealer Benefits

• Deep-Reach Versatility: The 30" throat depth is a premium feature, allowing your shop to take on larger enclosures and automotive panels that standard 18" or 24" machines cannot handle.
• Heavy-Gauge Specialist: 100 KVA provides the "punch" necessary for high-strength steels and 10-gauge+ mild steel without taxing the machine.
• Ready for Modern Production: The Weltronic digital upgrade ensures the machine meets modern QC requirements for documented weld schedules.
• Rigid Cast-Frame Construction: Built during Acme’s "over-engineered" era, the frame offers zero-flex operation under high electrode pressure.
