MIG · TIG · STICK · PLASMA
Start with metal, thickness, process and available input power. Then compare output range, polarity, wire-feed path and duty cycle before a machine reaches the floor.
PROCESS INDEX
Each row isolates the question that changes equipment choice, without hiding process limits behind a generic product label.
For repeatable wire-fed work on steel and stainless steel; confirm transfer mode, shielding gas, feeder configuration and the amperage needed at the target duty cycle.
For controlled heat input and bead profile; distinguish DC work from AC aluminum needs, then review high-frequency start, pulse controls and cooling requirements.
For field repair, structural work and access-constrained jobs; match electrode class, open-circuit behavior, cable length and generator compatibility.
For separating conductive plate; compare clean-cut thickness, severance capacity, torch consumables, air quality and available input current.
For mixed-process shops; map the actual weekly workload before paying for modes, accessories or output capacity that the cell will not use.
READ THE NAMEPLATE
A useful comparison records the test condition beside the number. Rated output without voltage, duty cycle or input configuration is incomplete.
Share base metal, thickness, joint position, available power and expected arc-on time. The reply can then focus on a workable process envelope.
