Input Connections

 

 

Make sure the voltage, phase and frequency of input power is as specified on machine rating 

plate located at rear of machine.

 

 

Have a qualified electrician provide suitable input power as per national electrical codes. Make 

sure machine is earthed / grounded.

 

 

Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers 

smaller than recommended will result in 

nuisance

’ 

shut off from welder inrush currents even if 

welding at low amperages.

 

Failure to follow these instructions can cause immediate failure within the welder and void ma-

chines warranty.

 

 

Turn the input power OFF at the mains switch & fuse box before working on this equipment. Have 

a qualified electrician install & service this equipment.

 

Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before 

working inside this equipment. Do not touch electrically live parts

 

 

The MIG181 Digital MIG Welder requires a 240V 50/60Hz supply. It requires a 16A supply. 

 

It comes with a 2.5 metre mains cable attached.

 

Connect wires according to national coding. 

 

Brown wire –

 

Live

 

Blue wire –

Green/Yellow Wire –

 

Earth (Ground)

 

 

Connecting to an Engine Driven Generator

 

If connecting this machine to an engine driven generator please ensure the following

 

Minimum Generator KVA Output –

 6.0 

KVA continuous Generator to be fitted with AVR 

(automatic voltage regulation) DO NOT USE ON A GENERATOR WITHOUT AVR

 

Connecting to a generator without the above minimum requirements 

 

will invalidate your warranty.
