Dave Graf
Regional Sales Executive

Before beginning a 30 plus year career in Industrial Sales and Sales Management, Dave was a professional musician for a 10 year span as a guitarist/vocalist/songwriter. He and his wife of 33 years Kathy, relocated from their hometown of Chicago in ‘97 to Scottsdale, AZ where they spend much of the year along with son Matt, daughter Kylie and wonder dogs Gracie and Rizzo (you can take the Cubs fans out of Chicago but….!)

Davi’s Expanded North American Support for Plate-Roll Buyers
Davi’s expanded North American support operation can make application testing, training, parts planning, and retrofit review more practical for 4-roll plate-roll buyers, but it does not replace machine-fit validation.

AMTEK APC 1200 Beam Coping: Plasma or Oxy-Fuel?
The AMTEK APC 1200 fits structural fabricators that need repeatable CNC coping, beveling, profiling, and related thermal cuts across beams and other structural profiles. Oxy-fuel remains the practical choice for thick sections and difficult access, while plasma can add throughput on thinner work only when the exact APC 1200 configuration, pierce limit, torch access, and cut-quality requirements are verified.

Prodevco PCR51 Beam Processing for Wide-Flange Beams and HSS
The Prodevco PCR51 combines beam drilling, robotic plasma coping, marking, and four-face HSS processing. Its strongest fit is mixed structural work that regularly moves between wide-flange members and square or rectangular HSS with multi-face connection features.

Sample Parts Must Prove the Akyapak Plasma Cutting Scope
A clean plasma-cut coupon is not enough to approve a heavy-fabrication project. Representative parts should prove the proposed Akyapak cutting scope, process repeatability, material flow, downstream fit, and installation interfaces before capital approval.

Plant Manager Sign-Off: Dedicated, Shared, or Outsourced Stainless Routes
A carbon-steel fabrication shop can take on stainless structural work only when its material route controls the contact points that create surface contamination and late-stage cleanup. This field guide helps plant managers choose a dedicated stainless route, controlled shared equipment, or outside finishing capacity.

Multi-Machine Automation Depends on the Handoffs
A multi-machine line is not ready for layout approval until each handoff defines part state, handling path, buffer behavior, control authority, recovery, access, and acceptance responsibility.

Akyapak ABM 76 CNC 3: The Changeover Case Starts With Tooling
The Akyapak ABM 76 CNC 3 is strongest when recurring tube families can use its three-die capability without forcing extensive support-tool changes. Routing history, tooling requirements, cell flow, and first-piece acceptance determine whether that flexibility will benefit the schedule.

Bridge Welding Automation Starts With an Accepted Part
The strongest first bridge welding automation scope is not necessarily the weld family with the most manual arc hours. It is the component that can move through engineering, fit-up, welding, inspection, repair, records, and outbound handling without an unresolved ownership or plant-flow gap.

Akyapak ABM 38 Fit Depends on Tube Envelope and Tooling
The Akyapak ABM 38 is not a nominal-diameter purchase. Confirm the actual tube geometry, material condition, tooling, handling path, and downstream handoff before approving the configuration.

The Automation Cell That Cannot Be Serviced
A compact automation layout can preserve production flow on a drawing while making cleaning, fault recovery, component replacement, crane access, and safe service work impractical. Treat service tasks as layout inputs before fence lines, equipment locations, and handling interfaces are fixed.

Plasma Cutting Capacity Is Decided at the Handoff
A plasma table creates usable capacity only when plate can be staged, cut, cleared, identified, ventilated, and delivered downstream without creating new queues. The approval decision belongs to the complete material flow, not table speed alone.

When a Liberty Systems Gas Mixer Is a Better Investment Than More Nitrogen Capacity
A Liberty Systems BRS gas mixer can be the better capital decision when recurring burr and dross on selected aluminum or mild-steel parts are creating downstream labor. Start with finished-edge acceptance, qualify the mixed-gas process, then size the gas system around peak demand.
