5 OPERATION
4. When working in a confined space, be sure it is safe to enter. The confined space should
be tested for adequate oxygen (at least 19%) with an approved oxygen measuring
instrument. The confined space should not contain toxic concentrations of fumes or
gases. If this cannot be determined, the operator should wear an approved air-supplied
breathing apparatus. Avoid gas leaks in a confined space, as the leaked gas can
dangerously reduce oxygen concentration in the breathing air. DO NOT bring gas
cylinders into confined spaces. When leaving a confined space, shut OFF the gas supply
at the source to prevent gas from leaking into the space. Check the breathing
atmosphere in the confined space to be sure it is safe to reenter.
5. Never operate the equipment at currents greater than the rated ampere capacity.
Overheating will occur.
6. Never operate equipment in a damp or wet area without suitable insulation for protection
against shock. Keep hands, feet, and clothing dry at all times.
7. Whenever the equipment is left unattended, turn OFF all control power, power supply
switches, and gas supplies. Open the main line switch.
8. Wear dark substantial clothing to protect exposed skin from arc burn, sparks, and flying
hot metal.
9. Turn off welding power before adjusting or replacing electrodes.
WARNING!
When the power switch is ON and the torch trigger is pushed, the electrode wire
becomes electrically hot and the wire feed rolls are activated. Do not touch the
wire as it may cause a possibly fatal shock. Unless welding, do not allow the wire
to touch a grounded metal surface as it will cause an arc flash. Keep clear of feed
rolls and drive gears.
WARNING!
Prior to welding, it is imperative that the correct protective clothing (welding coat
and gloves) and eye protection (glasses and welding helmet) be put on. Failure to
comply may result in serious injury.
CAUTION!
Do not terminate the arc by removing the torch from the weld area. Release the
torch trigger to stop welding before removing the torch.
WARNING!
Failure to turn off the shield gas in a confined space may result in a buildup of
fumes, displacing oxygen.
