We combine our orbital welding expertise with a practical approach to offer the most complete orbital welding rental and lease services in the market.  All CSI equipment is upgraded with more precise and durable tooling, resulting in better welds & increased productivity.

Fully Reconditioned After Every Rental Return

CSI’s orbital welding rental and lease equipment is carefully checked and reconditioned before being sent to a customer.   Every rental/lease component – the power supply -weld head – cables – undergo a full evaluation.   CSI features Arc Machines (AMI) tube welding equipment, and we are AMI’s exclusive Authorized Service Center in the U.S.


The M217 is AMI’s replacement to the M207 power supply, which has long been the standard for tube welding in the US.  The following article provides an “Under-the-Hood / First Look” at the M217, and compares it to the M207.

Competitive Rental Rates and Quick Turnaround

Because we constantly recondition of our rental fleet, CSI’s rental equipment will not only out-perform, but will also out-last the units from other rental companies.   As a result, we can pass that savings along to our customers.     Furthermore, our large rental inventory enables us to provide next day or 2 day delivery on orbital welding systems with commonly used weld head sizes.

Critical Systems stocks a wide variety of consumables, as well as facing tools, orbital weld heads, collets, adapter cables, and more.  We also have used systems to sell.
