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.   
On multiple voltage input welders, be sure the machine is connected as per the instructions for the voltage being 
supplied to welder    Failure to follow these instructions can cause immediate failure within the welder and void 
machines warranty.   
 
 

WARNING!   
 
ELECTRIC SHOCK CAN KILL   

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 POWER MTS210D Inverter TIG Welder requires a 240V 50/60Hz 20 amp fused supply.   
It comes with a 3 metre mains cable attached.   
 
Connect wires according to national coding. (Below states UK coding) 
Brown wire - Live, Blue wire - Neutral, Green/Yellow Wire - Earth (Ground) 
 

Connecting to a mains electrical supply

   

 

THIS MACHINE IS OF AN INDUSTRIAL SPECIFICATION AND MUST BE   

FITTED TO A 20AMP 240V MAINS INPUT     

 

Connecting to an Engine Driven Generator 

 

If connecting this machine to an engine driven generator please ensure 

the following Minimum Generator KVA Output – 7.2 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.
