Market guide
Choose process, power and aluminum path
Define the welds and electrical service before comparing maximum outputA multiprocess label does not mean every process, metal and input condition is equally capable. Start with the qualified work, then choose the machine branch that supports it without adapters, undocumented settings or missing hardware.
Work
Name the metal, joint and procedure
Record base metal and coating, thickness range, joint, position, filler, required process, duty and any governing procedure or code before selecting a power source.
- Qualification
- Presets and programs do not qualify an operator, procedure, structural weld or safety-critical repair.
- Preparation
- Identify coatings, cleaners and SDS hazards before heat is applied.
Aluminum
Choose the exact aluminum path
Spool-gun MIG, push-pull MIG and AC TIG solve different aluminum work. Verify wire, gas, torch, liner, feeder and supported program rather than relying on an aluminum-ready label.
- AC
- DC TIG is not an AC TIG aluminum process.
- Package
- Retain whether the spool gun, push-pull gun, TIG torch, pedal and regulator are included or optional.
Input
Match the rating label to the available power
Output and duty change with input voltage and phase. A qualified electrician must size the receptacle, branch circuit, grounding, disconnect, extension lead and generator from the exact manual and rating label.
- Adapters
- Dual-voltage capability is not permission to use an improvised adapter or undersized circuit.
- Site
- Wet areas, confined spaces, generators and long leads need their own documented control plan.
