FIELD FAQ
Welder hire questions
- What welder do I need for site work?
- An engine-driven welder is common where no mains power exists. Choose amperage and duty cycle for the thickest material and longest runs.
- Are consumables included?
- Rarely. Rods, wire, gas and grinding discs are normally supplied by the user or charged separately.
- Can a welder power other tools?
- Many engine-driven welders have auxiliary power outlets. Check the rated output before running grinders or lights.
