Side by side
How we picked
The pool contains 11 listings whose titles name aluminum welding (Aluminum welding: yes). Each listing is compared on the details stated in its title: amps, process, input voltage, pulse, and the mention of a spool gun. The ordering rule is by stated amps (highest first); listings that state no amps come after those that do. Among ties, the number of stated yes details among pulse, dual voltage, and plasma cutter decides the rank, then the order in the pool. At most 3 picks from any one brand; at least 3 brands and 3 processes appear. All machines are compared on stated details and live prices.
How to choose
MIG, TIG, stick or multi-process
MIG and flux core welding feed a wire from a spool. TIG uses a tungsten torch with a separate filler rod. Stick uses coated electrodes. Multi-process means the title names MIG, TIG and stick together. For aluminum, many titles name MIG with a spool gun or AC/DC TIG. A multi-process machine listed here combines several processes in one unit.
What the amps on a title mean
The top output stated in amps is printed in the listing title. Higher amps means the maker rates the machine for more output. In this pool, amps range from a stated 250 down to machines that do not state amps. Compare the numbers listed: higher numbers generally indicate a machine with a higher rated output.
120V, 240V or dual voltage: read the title, then the manual
Some titles state the input voltage as 120V, 240V, or dual voltage. A dual voltage machine can be connected to either supply as the manual directs. Always follow the maker's manual and local electrical rules. This guide cannot say which outlet a machine plugs into.
Aluminum and pulse words on a listing
When a title names aluminum, the seller is describing the machine for use with aluminum. Pulse or double pulse is a mode described by makers as varying the current. Some machines here state pulse or double pulse. AC/DC TIG machines are described for aluminum because AC output is used for that metal.
Welder and plasma cutter combos
None of the listings in this pool name a plasma cutter. The guide covers only machines whose titles name aluminum welding; combos that also cut are not present here.
What this guide leaves out (and why)
The catalogue has no data for duty cycle, metal thickness, weld quality, bead appearance, penetration, arc stability, spatter, ease of learning, wire feed smoothness, durability, build quality, reliability, portability beyond a stated word, weight, noise, sales, or popularity. The maker's manual is the place for those details.
Questions
What does 'aluminum welding' mean in a listing title?
When a title names aluminum welding, the seller is describing the machine for use with aluminum. It typically means the machine is an AC/DC TIG welder or a MIG welder that comes with or can use a spool gun. This guide includes only listings whose titles name aluminum.
Does a higher amp number mean the machine can weld thicker aluminum?
A higher stated amp number means the maker rates the machine for more output, but the catalogue does not have thickness data for any aluminum. For thickness capacity, consult the maker's manual. This guide compares only the stated amp numbers in the listings.
Why do some listings not state amps or input voltage?
The seller's title does not always include every detail. When amps or input voltage are missing, this guide marks them as not stated by the seller. No guess is made. Compare the details that are stated.
What is the difference between pulse and double pulse?
Some listings state pulse or double pulse. Makers describe pulse as a mode that varies the current; double pulse is a further variation. The catalogue has no measurement of how these modes perform. The terms appear as stated in the title.
Does this guide cover duty cycle, weld quality or safety?
No. The catalogue has no data for duty cycle, weld quality, penetration, or safety beyond what the title states. Duty cycle and safe use are found in the maker's manual. Follow the manual and local electrical rules for installation and operation.
Why is there no plasma cutter in this guide?
This guide is filtered to listings whose titles name aluminum welding. None of those listings also name a plasma cutter. A separate guide covers welder and plasma cutter combos.
