Filter the MIG Welders inquiry cards, then open a quote dialog. An aluminum mig welder card records a configuration to ask about. It is not a shelf quantity.
No inquiry option matches that search. Clear the filter or describe the machine in the quote dialog.
Aluminum wire is softer than carbon-steel solid wire, so the feed path is the first split among offers. Write whether the buyer can accept a spool gun at the weld, a push-pull gun, or a short standard torch. Ask the supplier which of those three the quoted model actually includes.
Record wire diameter in inches or millimeters, for example 0.030 in or 0.035 in, and the spool weight the feeder is built to hold. A photograph of a similar gun does not prove the liner, drive-roll groove, or contact tip on the proposed bill of materials.
Base thickness belongs in the same sentence as the process. Thin sheet and a heavier bracket do not share one output setting. Ask for the thickness window the procedure was written for, and keep oxide removal, joint fit-up, and travel direction as buyer notes rather than assumed factory features.
Shielding gas for aluminum is commonly an argon question, including purity and flow. Do not copy a cylinder specification from a public catalog into the purchase order until the proposed supplier repeats it for the exact model. If the site has no gas manifold, say so. That single fact changes hose, regulator, and cylinder handling.
Input power still needs volts, hertz, and phase. A 230 V, 60 Hz, single-phase receptacle is an example of how to write the utility, not a default for every machine. Duty cycle should name the current and the ambient temperature. A 200 A mark at 60% is not the same screening point as 200 A at a shorter cycle.
Pulse controls, inductance, and wire-feed speed repeatability matter when the work is repetitive. Ask whether those controls are on the quoted control interface or sold as another board. Ingress protection matters if grinding dust or outdoor moisture reaches the cart. Noise level matters if a fume extractor is added beside the station and was omitted from the machine price.
Compare delivered cost only after tips, liners, spare parts, packing, freight, and the commissioning scope are either included or excluded in writing. A specification deviation list should show every departure from the brief. Read the quotation scope page, the workflow, and the brief note before you submit the aluminum requirement.
