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 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 grunded 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) are put on. Failure
to comply may reult 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 shield gas in confined space may result in a build-up of fumes,
displacing oxygen.

Setting a welding procedure

Quick set-up procedure
1. For Constant Voltage (CV) Power Source; Set the desired arc voltage on the power
source.
2. For Constant Current (CC) Power Source; Set the desired weld current on the power
source.
3. On the MobileFeed unit: Set the desired wire feed speed with the knob for the wire
feed speed and use the values shown by the display as guidance.
A feeder in CV mode will show the actual wire feed speed while welding.
A feeder in CC mode will show a wire feed speed that varies with changes in arc
voltage. When not welding, the display will show what the wire feed speed will be at
the displayed voltage.
