Using Shielding Gas Efficiently

Gas handling equipment is one area shops sometimes overlook to keep costs down to stay competitive. Proper gas-saver flowmeter regulators can ensure saving on the amount of shielding gas that is used with each pull of the trigger of the welding gun.

Clearing the Air in Gas Delivery

MIG and TIG welding, plasma cutting, laser cutting or welding all require compressed gases. How these gases are stored, handled and used will determine the extent that the overall cost of these gas products impacts your bottom line. The correct gas delivery system will provide the most economical and efficient results to complement any of these applications – and the normal starting point for all of them is a cylinder of gas and a regulator. 

Why You Need Gas and Equipment Savvy for a Second-Hand Laser

A factory-reconditioned or second-hand laser is a good way to increase shop productivity at a fraction of the cost of a new machine. Incorporating these principles and pointers into the purchase and installation of a second-hand laser should assist you in achieving first-class efficiency and operation.
