LES RAYONS D’ARC peuvent entraî- ner des brûlures aux yeux et à la peau. Le rayonnement de l’arc du procédé de soudage génère des rayons visibles et invisibles intenses (ultraviolets et infrarouges) susceptibles de provo- quer des brûlures dans les yeux et sur la peau. Des étincelles sont projetées pendant le soudage.

SECTION 4 − INSTALLATION - POWER SOURCE 4-1. Selecting a Location Dimensions And Weight 73 lb (33.1 kg) Movement Location 18 in (460 mm) OM-216 244 Page 10 24 in (610 mm) 12-1/2 in (318 mm) Y Do not move or operate unit where it could tip.
4-2. Electrical Service Guide CAUTION: INCORRECT INPUT POWER can damage this welding power source. This welding pow- er source requires a CONTINUOUS supply of 60 Hz (+10%) power at +10% of rated input voltage. Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.
4-3. Weld Output Receptacles 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.
4-4. Connecting 3-Phase Input Power Tools Needed: = GND/PE Earth Ground Y Installation must meet all National and Local Codes − have only quali- fied persons make this installation. Y Disconnect and lockout/tagout in- put power before connecting input conductors from unit. Y Always connect green or green/ yellow conductor to supply grounding terminal first, and nev-...

8-3. Maintenance Procedures for Stud Gun When is Maintenance Required? Maintenance requirements will vary with environment and usage. Dirty work areas or high volume stud welding will require more frequent main- tenance. There are three primary reasons for maintenance: Dirt - Dirt can enter the lifting mechanism and cause erratic lift and plunge operations.
