Most of the references claim that it is possible to spot weld Aluzinc sheet. Do I need any special equipment though?

RE: spot welding aluzinc sheets
"Welding
GALVALUMEĀ® steel sheet can be welded by conventional resistance and arc welding processes. The safety precautions are similar to those for hot-dip galvanized sheet.
Because the surface contact resistance is low when compared with uncoated sheet, resistance welding of GALVALUMEĀ® steel sheet requires welding currents, welding times and electrode forces higher than those required for similar thicknesses of uncoated cold rolled steel. These welding parameters are similar to those normally used on galvanized steel. However, experience has shown that even more frequent electrode dressing is required, as compared with galvanized sheet, to achieve good welds."
Typical parameters (tables) for spot and seam welding of Galvalume sheet are given in Galvalume Technical Bulletins (pg. 2) at
