How to Choose a Used Miller Welder
Before purchasing a used Miller machine, consider:
1. Welding process
Do you need MIG, TIG, Stick or multiple processes?
2. Amperage
Choose an output range suitable for the materials and thicknesses you weld.
3. Duty cycle
Consider how long the machine needs to weld continuously.
4. Portability
A shop welder and a truck-mounted engine-driven welder have very different requirements.
5. Auxiliary power
For engine-driven machines, determine how much generator power you need for grinders, lights and other tools.
6. Condition
Evaluate the individual machine’s hours, maintenance, controls, cables, engine and overall condition.
Miller Multiprocess Welders
Considering a multiprocess welder. If your application requires you to weld using MIG, TIG or Stick more or less interchangeably, then multiprocess capabilities may offer value to you. Miller has several machines in their Multimatic family which can produce MIG, TIG, and Stick output in a single power source. It makes a tremendous sense for job shops, or field contractors that don’t want the equipment investment and space taken up by individual machines.
Why Buy a Used Miller Welder?
Buying used can reduce the initial equipment investment while giving you access to professional equipment.
However, condition matters.
