HPC LASER
heights , as you can lower the bed to allow space for bigger items . This does not change the depth of the lasers cut , but is still an important feature if you ’ re considering working or experimenting with different sizes , or if you wish to install a rotary attachment for engraving cylindrical objects .
Suppliers and Distributors
When searching for a supplier or distributor to buy a laser from there are a few things to look out for . Firstly , a company with good feedback and reviews . You can find them on a number of sites , from Facebook to Trustpilot . Reviews are a great way of getting an insight into a company and what you can expect if you decide to use them . A business with experience , quality customer service and that can provide maintenance support is essential when purchasing equipment as specialised as a laser cutter . To quote a recent customer “ Until you ’ ve owned a laser and built your business model around it , you may not understand how important after sales service actually is . Trust me , it ’ s critical !”
HPC Laser offers free of charge lifetime email and telephone technical support should you need it at any point in the future . Whether you ’ re cutting for fun or have client demands to meet , if you have any questions about your machine you don ’ t want to be waiting on a reply for weeks .
These points may sound fairly obvious , yet many people still rush to make a decision solely based on the price of a product .
Buying Cheap
If the price seems too good to be true , it probably is . There are many sellers that sell cheap machines with little , if any quality control measures in place . They often use substandard components with little attention to detail and often arrive differently to as ordered , sometimes even broken . Parts need replacing more frequently , and without warranty , servicing or expert technical support , your experience is suddenly much more complex than it needs to be . There have been many UK suppliers over the years
that have set up supplying laser machines , only to quickly go out of business when their customer base needs support and backup .
Most importantly , they don ’ t always comply with safety regulations and procedures ( such as CE ) which can be extremely dangerous considering the function and power of these machines .
Chiller Units
Water cooled CO2 laser machines need to be cooled continuously using a water source that can consistently keep the water temperature below 25 ° C . A water chiller from HPC will reliably keep your water temperature between 5 ° C and 25 ° C when paired with laser machines up to 150W ! They also offer upper and lower temperature alarms and an alarm to warn of flow restrictions , ensuring that you do not permanently damage your laser tube through insufficient cooling .
Ensure you have the correct Chiller Unit
The size of these systems varies broadly depending on application , from portable to freestanding . It ’ s important to use a chiller powerful enough for your machine ; larger cutters cannot be regulated by low power chillers .
You may be given a chiller or pump as part
of your machine package , which is great , just be sure that it ’ s appropriate for the machine you ’ re running . If you are in any doubt , please contact HPC Laser for some reassuring advice .
Water temperature affects performance and functionality . If the water is too hot , the lasers performance will suffer and the machine is likely to overheat . This can lead to permanent damage to your machine , particularly your tube .
If water freezes in the chiller , the motor can be damaged , and internal water circuits begin to crack . Obviously , this prevents the chiller from working properly which again can lead to overheating but can also cause irreparable damage . To avoid this you can use antifreeze coolant such as LS Coolflow . For more information on chillers and general maintenance read How to Maintain and Service Your Laser Machine Effectively .
