Megatec PROMIG 250T

Description

The Megatec PROMIG 250T is a rugged, transformer-based industrial MIG/MAG welding machine designed for heavy-duty fabrication and automotive repair. Engineered for durability and ease of use, the “T” designation signifies its Transformer core, offering a traditional, stable arc that many veteran welders prefer for its reliability in harsh workshop environments. Operating on a three-phase \(380\text{V}\) power supply, the PROMIG 250T provides a consistent \(250\text{A}\) output, making it ideal for continuous welding on mild steel, stainless steel, and aluminum.

Key Features:

• Heavy-Duty Transformer Design: Built with a high-quality copper-wound transformer that provides excellent heat dissipation and a long service life, even under high-load industrial conditions.
• Multi-Step Voltage Adjustment: Features a stepped voltage control switch, allowing the operator to precisely click into the required power setting for different material thicknesses.
• Integrated 4-Roll Wire Drive: Equipped with a professional-grade 4-roll geared wire drive system. This ensures positive, slip-free wire feeding, which is essential when using longer \(4\text{m}\) or \(5\text{m}\) torches or soft aluminum wires.
• Burn-Back & Spot Weld Control: Includes adjustable burn-back settings to prevent the wire from sticking in the weld pool, as well as a dedicated spot-welding timer for consistent repetitive tacks.
• Digital Display Meters: Features clear, easy-to-read digital volt and amp meters for real-time monitoring of welding parameters, ensuring compliance with welding procedure specifications (WPS).
• Industrial Undercarriage: Comes standard with a heavy-duty trolley, large rear wheels, and a dedicated cylinder platform, allowing for easy maneuverability of the machine and a full-size gas cylinder around the workshop.

Technical Specifications:

• Input Voltage: \(380\text{V}\) Three-Phase (\(\pm10%\)).
• Current Range: \(40\text{A}\) to \(250\text{A}\).
• Duty Cycle: \(250\text{A}\) at \(60%\) / \(190\text{A}\) at \(100%\).
• Voltage Steps: 10 Steps for fine-tuned control.
• Wire Spool Capacity: Standard \(15\text{kg}\) (\(300\text{mm}\) diameter).
• Protection Class: \(IP21S\).
• Weight: Approximately \(85\text{kg}\) (Rugged industrial build).
