Page 8: Features & Applications
ARC-E 400 Features & Applications ARC-E series inverter arc welding machines are manufactured in line with the following standards: GB15579, 1-2004 “ARC Welding Equipments· Part One· Power Source”. This series machines are SMAW machines with different specifications of rated current: 315A, 400A, 500A, which are novelty high-efficient and energy-saving DC Arc welders, not only are used in carbon steel and low alloy steel welding, but also used in stainless steel, high alloy steel, copper, silver, molybdenum and titanium welding.
Page 9: Installation Guide
ARC-E 400 Installation Guide 1． Pre-installation 1.1 Installation Environment The ARC-E series is designed for use in adverse environments. Examples of environments with increased adverse conditions are:  In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts;...
Page 10 ARC-E 400 1.3 Power Source Connections Warning Thermal Arc advises that this equipment be electrically connected by a qualified electrician. ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is present after removal of input power. DO NOT TOUCH live electrical parts. ...
Page 11 ARC-E 400 2. Installation The machines are portably designed, can be effortlessly moved by operators without fix-up. But it should be settled in even and dry places with well ventilation. (1) Ensure the welding cable be connected to the power source firmly. (2) Adjust every knobs, and switches on the front panel to proper position in line with selected mode.

Page 15: Repair & Maintenance
ARC-E 400 Repair & Maintenance WARNING: Have a qualified electrician do the maintenance and trouble shooting work. Turn the input power off, using the disconnect switch at the fuse box before working inside the machine. 1. Cautions  Rivet equipment name tag on the specified area of the case, otherwise the inside parts will possibly be damaged.
Page 16: Arc-E
ARC-E 400  Check if the input volt has the phase missing, and range are between 340~420V.  Check if the input cable is connected correctly and firmly with the power source.  Check if the welding cables are connected correctly and firmly. WARNING: Have a qualified electrician do the maintenance and trouble shooting work.
Page 17 ARC-E 400 Appendix A 1. General The user is responsible for installing and using the arc welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected, then it shall be the responsibility of the user of the arc welding equipment to resolve the situation with the technical assistance of the manufacturer.
Page 18 ARC-E 400 3. Methods of reducing emissions 1) Public supply system Arc welding equipment should be connected to the public supply system according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the public supply system. Consideration should be given to shielding the supply cable of permanently installed arc welding equipment, in metallic conduit or equivalent.
Page 19 ARC-E 400 bonding should be achieved by suitable capacitance, selected according to national regulations. 6) Screening and shielding Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications.
