Which one would we shortlist?
Choose the ALW-1200A first when lower purchase price, smaller footprint and portability matter more than integration. Move to the ALW-1400 when the built-in wire feed, self-generated shielding-gas design and higher published steel/copper capability justify the price and weight.
Two things the wattage does not tell you
FacilityBoth are 220V systemsThe 1400 publishes a 20A requirement; the 1200A publishes 4 kW rated input. Verify the actual circuit with the seller/electrician.
Workflow32 kg vs 94 kgThe physical deployment difference can matter more than 200W of output.
