Welding machine calibration
We calibrate welding machines with a load bank, checking that the voltage and current the machine displays match its actual output. Used by more than 25 fabrication and welding clients.

Why it matters
Welding procedures set the voltage and current ranges a weld must be made within. If the machine's meters are out, welders can be working outside the procedure without knowing it. Calibration supports fabricators working to AS/NZS 1554 and ISO 3834, where welding equipment needs to be shown fit for use.
For welding procedures, inspection and certification support, see our sister business, Professional Welding Clinic.
Tell us about the machines
Send the make, model and welding process (MIG, TIG, stick and so on) for each machine, how many need checking and where they are. Include any voltage, current or report requirements from your customer.
What your report includes
Each machine gets a NATA-traceable report that identifies it by make, model and serial or equipment number, and records the voltage and current checks, the reference values and the readings, with the date of the work.
Before you book
Calibration checks the machine’s readings against its actual output. It is not a repair or a full electrical safety inspection. Ask us separately about test and tag if you need it.
Common questions
Is this calibration or verification?
Calibration. We put the machine under load with a load bank and compare its displayed voltage and current with measured values.
Do you come to our workshop?
Yes. Welding machines are usually calibrated at your site so there’s no downtime moving them.
Which standards does this support?
Machine calibration supports fabricators working to AS/NZS 1554 (structural steel welding) and ISO 3834 (welding quality requirements), where equipment needs to be maintained and shown fit for purpose.
How often should welding machines be calibrated?
Usually every 12 months, or as required by your quality system or customer.
Can you test and tag the machines too?
Yes. Electrical test and tag is a separate service. Mention it when you ask for a quote and we can plan both together.
