3)The area where the surrounding temperature is in 10~40°C range.
4)The altitude of the location shall not higher than 1000m above the sea level.
3 3 . Cautions in grounding
1)The welder must be grounded, or electrical current of the case causes the unstability of
operation and accidents.
2)Connect grounding conductive cable which is 10SQ or more to the grounding terminal which is
marked "Grounding". During the grounding work, make sure to off the on/off switch in the
switch board, and afterward connect the ground cable.
3)When the base metal is placed on insulator such as wood, the base metal must be grounded.
4)When there swimming pool or pond between the earth of power source switch board and the
earth of welder, leakage current may flow to the pond or swimming pool. So in such place,
please connect grounding to both grounding points in parallel so that the leakage current flow
through the cable.
3 4. Capacity of power facility
Please use this welding machine at a rated input voltage. Since the welder is installed with a
building out network for input voltage, it will operate normally within a range of ±10% of the
input voltage. Any excessive input of voltage beyond the allowance can result in failure.
3 5 . Ventilation
CO2 arc welding resolves shield gas, CO2 in high temperature and produces few carbon
monoxide, Therefore, please ventilate properly when welding is carried out in a small space.
3-6 . Carbon dioxide
Please use KS No.3 or the one specified for welding.
3-7. Connection of electrical sys (Off the on/off switch in the switchboard)
Even one point of defective connection may cause unsatisfactory welding quality. Please tighten
the connection cables firmly with tool.
1)Connection of input power : Please connect referring to the Fig. 1. Install NFB for your safety.
When you install the electric leafage breakers, please install the one which can detect more
than 30mA.
2)Connection of output : Referring the Fig 1, please connect the torch to (+), base metal to ( ).
3)Connection of control cable: Connect the control cable to remote terminal in order to control
welding wire feeder and remote control box.
