Page 4: Technical Specifications
Welding Capability – Duty Cycle The R-Tech PROARC135 is rated at 135 Amps at 35% duty cycle on a ten minute basis. If the duty cycle is exceeded a thermal protector will shut machine off until the machine cools. - Page 5 Safety Precautions Read entire section before starting installation WARNING! Electric Shock can kill – Only qualified personnel should perform this installation. Turn off input power at the fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine to an earthed mains supply as per national recommended standards.

Page 6: Electric Shock Can Kill
Machine grounding and Interference Protection This welder must be grounded to earth. See national electrical codes for proper grounding methods. Radiated interference can develop in the following ways 1. Direct interference from welder power source 2. Direct interference from the welding leads 3. - Page 7 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 PROARC135 Inverter Welder requires a 240V 16A 50/60Hz supply (at 125 amps output it will draw 13A input, if used on a 13Amp plug you may get nuisance fuse blows when welding at maximum amperage).
