Recommended Processes 

 

The R-Tech PROARC175 is recommended for the MMA welding processes within its output 

capacity of 175 Amps DC 

 

Equipment Limitations  

 

The R-Tech PROARC175 is protected from overloads beyond the output ratings and duty cycle as 

per machine specifications with thermostat protection. 

 

 

Welding Capability – Duty Cycle 

 

The R-Tech PROARC175 is rated at 175 Amps at 20% duty cycle on a ten minute basis. If the duty 

cycle is exceeded a thermal protector will shut machine off until the machine cools.
