The machine suddenly stops
welding operations after an
extended and heavy-duty use.
8. SAFETY RULES
Welding can be dangerous to both operator and bystanders. The following safety rules are strongly recommended.
Personal cautions!
Wear suitable clothing, possibly without protruding pockets and turn up and avoid synthetic materials.
Always wear welding gloves.
Wear heavy duty shoes, high laced with steel caps.
Always use a welding mask fitted with a suitable dark lens, which have also a side protection.
Caution: gas fumes!
Ensure a good ventilation of the work area. If necessary, use an aspiration plant, above all in small working rooms.
Clean away from the work piece any rust, grease or paint to reduce fumes as much as possible.
Caution: short-circuit risk!
Make sure the electric net is provided with adequate earthing and protection against overloads and short circuits.
Make sure that all the main cables, torch, earth are in good conditions and replace if necessary.
Connect the earth cable firmly to the workpiece.
Do not wrap earth or torch cables around the body.
Do not point the torch towards people.
Avoid welding in wet or excessively damp conditions.
Do not operate the machine with its side panels removed.
Do not touch the contact tip on the torch or the workpiece.
Caution: explosion risk!
Do not weld in the proximity of inflammables.
Ensure the welding machine is positioned on a flat, stable level.
Tie the gas bottle to the machine with the chain provided, away from sources of heat.
Make sure you are using the correct gas mixture and the gas reducer is of a proved type and that it works properly.
Don't use the machine for a tube defrosting activity.
The machine has an IP 21 protection level - it is not to be used or stored in the rain!
9. REPLACEMENT OF THE MAINS CABLE
Any replacement mains cable must be of suitable quality and of the same dimensions as the original:
Models EASYCRAFT 100, 130, 145, 150; WEMIG 150, 150D;NW 100/2, 101/2,130, 150, 170 = 3 x l,5 mm
For fitting a replacement cable, note the following instructions:
1)
Prepare the cable by stripping the outer sheath and inner wires at the two ends. On the machine side, the length of the
neutral and lives wires between the cable anchorage and clamps should be such that they would tighten before the
earth wire in the event of the cable becoming loose from its anchorage.
2)
Remove the right side of the machine's casing, undo the cable guide and remove the old, faulty cable.
3)
On the machine end of the new cable, fit fastons to the bare blue and brown wires and an eyelet type to the earth wire.
4)
Thread through the cable guide and connect the cable to the terminal block as follows : - brown wire to the black
terminal, blue to the blue terminal and fit the green / yellow earth lead using a nut and shakeproof washer. Ensure
all connections are well tightened.
N.B. In case of difficulties ask for qualified help.
3) Too small gas flux
4) Humid workpieces
5) Heavily rusted workpieces
1) Welding machine overheated
due to an excessive use
in stated duty cycle
- 17 -
in relation to workpiece
Increase flux of welding gas
Dry with heat producer
Clean workpieces from rust
Don't switch off the machine,
leave it to cool down
for about 20/30 minutes time.
