  The arc welder is restricted in Australia to a maximum of 80 volts (open circuit) on the welding power side and at this voltage it may generally be considered as "safe". Dry gloves, dry Buckboards or heavy leather boots (not hobnailed) or preferably rubber shoes are effective additional barriers.

  With the welding plant switched on, N0- or Open-circuit voltage and before welding commences, no current passes through the leads and the arrimeter reads zero. A voltage has been applied to the circuit, however, and the voltmeter will read the open-circuit or no-load voltage (i.e. between 60 and 100 V). Creating an arc – stage 1.
