Buying welders
Is it worth buying used multi-process welders?
Quick answer
Used multi-process welders can be strong value at 40–60% of new price if the machine powers on, strikes an arc at rated amps and the seller is upgrading (not dumping). Avoid ex-site abuse: cracked cases, smoke residue and missing panels are the tells of a machine near death.
Used-buying inspection
- Power on, fan runs, no error codes
- Strike a test arc at ~half and near-max output
- Inspect torch/leads for damage and DIY repairs
- Ask why it's for sale — upgrades are fine, 'just cleaning up' is not
- Check consumable availability for that model before you buy
Depreciation logic
Quality inverters hold value surprisingly well in Australia — a $1,300 trade MIG resells around $600–$800 for years. That cuts both ways: used bargains on good machines are rare, and used bargains on cheap machines aren't bargains.
