Point to point welding
Point to point welding is necessary then when the seam to be welded does not withstand heat of
continuous arc and welding has to be carried out by interrupting arc. The reason is usually thin
materials or variable ttings.
The machine has characteristic curve which makes interrupting of arc easier when electrode is
drawn further from seam.
6. maIntenance
The amount of use and the working environment shoud be taken into consideration when
planning the frequency of maintenance of the machine. Careful use and preventive maintenance
will help to ensure trouble-free operation.
6.1. cables
Check the condition of welding and connection cables daily. Do not use damaged cables.
Make sure that the mains cables in use are safe and according to laid down regulations.
The repair and mounting of a mains connection cables should be carried out only by an
authorized electrician.
Carbon arc gouging
In carbon arc gouging there are dynamic constant voltage curves. If the tip gouging carbon
makes a short circuit, the power source will make an strong increase to the current, the short
circuit ends rapidly and the arc will remain or reignite easier.

7.3. under- and overvoltages In the maIns supply
Primary circuits of machine are protected against sudden, transient overvoltages.
Machine is designed to withstand 3 x 440 V voltage continiously (see technical data). See to
it that voltage is kept within admissble limits especially when mains supply is taken e.g. from
combusition engine generator.
If the mains has undervoltage (under approx. 300 V), machine control stops to operate automa-
tically.
7.4. loss of a phase In the maIns supply
Loss of a phase causes noticeable poorer welding properties than normally or the machine
doesn’t get started at all. Loss of a phase can be due to following:
- blowing of mains supply fuse
- defective mains cable
- bad connection of mains connection cable on terminal block or plug of machine
7.5. dIsposal of the machIne
Do not dispose of electrical equipment together with normal waste!
In observance of European Directive 2002/96/EC on Waste Electrical and Electronic
Equipment and its implementation in accordance with national law, electrical equipment
that has reached the end of its life must be collected separately and returned to an
environmentally compatible recycling facility. As the owner of the equipment, you should
get information on approved collection systems from our local representative.
By applying this European Directive you will improve the environment and human
health!
