CYLINDERS can explode if damaged. 4. Never drape a welding torch over a gas cylinder. 5. Never allow a welding electrode to touch any cylinder. Shielding gas cylinders contain gas under high 6. Never weld on a pressurized cylinder − explosion will result. pressure.
OVERUSE can cause OVERHEATED SIGNIFICANT DC VOLTAGE exists after EQUIPMENT. removal of input power on inverters. 1. Allow cooling period. 1. Turn Off inverter, disconnect input power, and 2. Reduce current or reduce duty cycle before discharge input capacitors according starting to weld again.
SECTION 2 − DEFINITIONS 2-1. Warning Label Definitions Warning! Watch Out! There are possible hazards as shown by the symbols. Electric shock from welding electrode or wiring can kill. 1.1 Wear dry insulating gloves. Do not touch electrode with bare hand. Do not wear wet or damaged gloves.

SECTION 3 − INSTALLATION 3-1. Selecting A Location Lifting Eye Lifting Forks Use lifting eye or lifting forks to move unit. Movement If using lifting forks, extend forks beyond opposite side of unit. Rating Label (Non CE Models Only) Use rating label to determine input power needs.
3-3. Tipping Y Be careful when placing or moving unit over uneven surfaces. 3-4. 115 VAC Receptacle And Circuit Breakers Y Turn power before connecting to receptacle. 115 V 15 A AC Receptacle Power is shared between RC9 and Remote 14 receptacle RC8 or terminal strip 1T (see Section 3-7).
3-5. Weld Output Terminals And Selecting Cable Sizes Y ARC WELDING can cause Electromagnetic Interference. To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed and grounded according to this manual.
3-7. Connecting Remote Control Remote 14 Receptacle RC8 Connect remote control to RC8. If plug does not fit, wire cord to termi- nal strip 1T. Y Turn power before opening terminal strip cover. Terminal Strip 1T Remote Control Cord Strain Relief (Customer Supplied) Secure cord in strain relief.

SECTION 4 − OPERATION 4-1. Controls Ref. ST-800 101-C Polarity Selector Switch (Optional On electrode. Remote Amperage Control Switch 50 Hz Models) For front panel control, place switch in Panel Set control at 0 for normal welding To change polarity on models not equipped position.
4-2. Duty Cycle And Overheating Duty Cycle is percentage of 10 min- utes that unit can weld at rated load without overheating. If unit overheats, thermostat(s) opens, output stops, and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before welding.
5-2. Fuse F1 Y Turn Off power before open- ing rear access door. Fuse F1 (See Parts List For Rating) Fuse F1 protects control transform- er from overload. If F1 opens, weld output and fan motor stops. Re- place F1. Tools Needed: 3/8 in Ref.
