Q: What is resistance welding?
A: It is method of connecting two metal elements. Natural metal’s characteristics is electrical resistance which is giving possibility to change state from solid into plastic and also with proper force – to connect them.
Q: What is the difference between pressure welding and soldering?
A: Welding by pressure is the natural process without using any additional materials. Very important is the pressure used while welding. Human factor is not needed, machine can count everything, select the best welding force and do the whole process from top to button. Pressure welding machine is able to work all the time, without any breaks and make lots of the same welds, the same, high quality.
Q: When pressure welding is used?
A: It is used when bigger output is predicted, when high quality, precision and reproducibility is needed.
Q: How can I know which machine will be the best for me?
A: On our website you can find out the most important information about welding. There are short videos and explanations. Knowledge about materials you want to weld is the half way to success. We do the rest.
Q: Is the purchase of welding involves employing specialized person? Do I need certifications, courses, long-term training?
A: No. In contrast to soldering this work doesn’t involve courses and trainings. Machines are easy to use just after short instructions. You can always ask for help our technical aid.
Q: Can I use one welder for different details?
A: Sure. Our machines are universal and all settings can be modified. Modern controls give us possibility to cooperate with lots of devices. Whats more welding machines are sold in lots of variants and configurations – that’s why they are so universal.
Q: What are conditions my company should comply with to use welder?
A: The only condition is the fact that electrical port to feed our welder is needed.
Q: Which components wear out and require replacement, and how often are required machine maintenance. How long is the warranty?
A: Every machine has a 12 months warranty. Wearing out depends on a few factors: how many welds has been done, how long machine has worked, what materials was used etc.
Q: I am interested in particular welder, but I am not sure if it will work with my materials. Can I try the welder on my own details?
A: Sure. Our specialist are able to make some tests on materials you are providing. Before buying the machine you can also do some research by yourself in ASPA’s testing station.
Q: What to do if welded elements are changing and new materials has a different texture or if manufacturing is totally changing?
A: Depending on the scale of modification, some settings’ or details changes or completely new machine.
Q: I want to buy electrode which will suit my resistant welder, how to choose the proper one?
A: Reading welder’s technical documentation you will find catalogue issue of the electrode you need. If you cannot have random access to welder’s documents, in catalog you can easily find the electrode needed and write down number to order it later – you can do it online as well.
Q: I want to weld lots of sheets, but they will not be the same. Can I change settings by myself?
A: Sure! Welders designed by ASPA are equipped with manageable electronic control, thanks to which we can select parameters of welding current. If you have any problems, doubts or questions, you can always contact us.
Q: Is it required to designate a special area on the floor to a welder because of the presence of the magnetic field during welding?
A: During welding, magnetic field is produced. Sometimes it can be dangerous. According to the Regulation of the Minister of Labour and Social Policy of 29 November 2002 on the maximum permissible concentrations and intensities of harmful factors (DZU No. 217 of 2002. Pos. 1833) in the vicinity of sources of electromagnetic fields should be designated and labeled areas of strong electromagnetic fields (danger zone, threats and indirect).Whether there is really such a zone can be seen only after the corresponding measurements under actual working conditions (at work welding with real operating parameters). After performing measurements may be that under actual working conditions (especially with the low-power welding machines) there are danger zones, or they do not go beyond the base sealers.
Production in ASPA acquired ISO 2008:9001 certification.
