Lincoln Electric Company offers a 500-amp welder, Vantage 500, in a compact case.
Lincoln Electric says it is the same size as the Vantage® 300 and 400 and achieves its compact size by the use of a turbo-charged diesel engine with the company’s Chopper Technology®. It weighs less than traditional 500-amp welders. All the features that have been standard on Vantage® products are here, including stainless steel enclosure, multi-process welding and plenty of AC generator power (single and three-phase).
The welder also includes a fifth weld mode for maximum arc-gouging output, VRD™ (Voltage Reduction Device™) and sealed GFCI (Ground Fault Circuit Interrupter) modules. 888-355-3213, http://content.lincolnelectric.com/pdfs/products/literature/mc0843.pdf.
