An AI sales agent's welding system order, checked before it goes out

An AI sales agent prepares an order for a Power Wave 300C welding system: the welding process, the gun, torch or electrode holder, the connection kits, the cooler, the TIG switch, the work cable and the weld cable, with the weld current the customer needs. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the setups the public Lincoln Electric connection guide lists and returns a verdict, every reason and the figures it computed.

Scope: Power Wave 300C MIG, TIG and Stick setups: guns and torches, connection kits, cooler, TIG switch, work cable and weld cable. See everything this validator covers

This validator models an order for a Power Wave 300C welding system, based on the public Lincoln Electric Power Wave Connection Guide (EDTS109A, October 2024), not just the scenarios shown below.

  • Process and torch — MIG with the Magnum PRO Curve HDE 250 gun, the Magnum PRO AI push-pull guns (air or water cooled), the 250LX GT spool gun or the K126 Innershield gun; TIG with the PTA-17F torch; Stick with the electrode holder; each torch against the process it is listed for.
  • Connection kits — gun connector kit K466-6 for the HDE 250 and K126 guns, the 7-pin to 12-pin adapter for the spool gun, the Cool Arc 40 cooler (water-cooled push-pull gun only) and its mounting kit, the K586-1 gas regulator kit on MIG setups, and a foot Amptrol, hand Amptrol or arc start switch for TIG.
  • Weld cable — the 14 electrode and work weld cables the guide lists, with their lengths and ampere ratings, against the weld current the order needs; an order that states a cable rating or length is checked against the guide.

Any Power Wave 300C order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the guide lists none, so this page shows no price build-up or line-item quote), wire feeders, ArcLink control cables, drive rolls and other Power Wave models. Assumptions: the weld current is read as the current at 60 percent duty cycle, and the rule that the weld current may not exceed a cable's listed ampere rating is generic logic applied to the guide's ratings, not a Lincoln Electric statement.

The AI sales agentBuilds the welding system order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Cooler only with the water-cooled gunOnly with care
Gun type and cooler are separate option lines, so each unavailable pair needs its own rule and a catalog update means editing them.		Gun and cooler arrive in one request and are matched to the guide on every call.
Connection kits that belong to a gunOnly with workarounds
The kit a gun needs lives on a different line from the gun, so a missing connector kit or adapter is usually found at assembly, not at order entry.		Gun, connector kit, adapter and cooler are checked together in the same call.
Torch against the welding processEasy
A process and torch pairing is a standard compatibility rule.		The same check, together with every other finding.
Weld current against the cable ratingOnly with workarounds
The rating is a property of each of 14 cables and the current is a separate field, so the comparison is usually left to a person.		Cable, its listed rating and the required current are compared on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The guide lists gun connector kit K466-6 with the Magnum PRO Curve HDE 250 and K126 PRO Innershield guns; the order has none.
2The guide lists the 7-pin to 12-pin adapter K2,910-1 with the Magnum PRO 250LX GT spool gun; the order has none.
3The Cool Arc 40 cooler K1,813-1 is listed for the water-cooled push-pull gun only.
4The guide lists the Cool Arc 40 cooler for the water-cooled push-pull gun and the order has none; a person should confirm how the gun will be cooled.
5Mounting kit K4,898-1 is listed as the mounting kit for the Cool Arc 40 cooler; the order has no cooler.
6The guide lists a foot Amptrol, hand Amptrol or arc start switch with the PTA-17F TIG setup; the order has none.
7The guide lists the selected gun, torch or electrode holder for a different welding process than the one on the order (MIG: the Magnum PRO guns and the K126 gun; TIG: the PTA-17F torch; Stick: the stick electrode holder).
8Every setup in the guide lists a work cable (with ground clamp); the order has none.
9The guide lists the K586-1 gas regulator, flowmeter and hose kit with every MIG setup and the order has none; a person should confirm the customer supplies one.
10The order needs 351 A of weld current; the selected weld cable is listed at 350 A in the guide.
11The order needs 326 A of weld current; the selected weld cable is listed at 325 A in the guide.
12The order needs 301 A of weld current; the selected weld cable is listed at 300 A in the guide.

14The order needs 601 A of weld current; the selected weld cable is listed at 600 A in the guide.
15The guide gives no ampere rating for the K2,163 4/0 weld cable; a person should confirm it suits the weld current.
16The order states a weld cable rating of 600 A; the guide lists 350 A for this cable.
17The order states a weld cable length of 50 ft; the guide lists 25 ft for this cable.
18The order has 0 welding systems; at least 1 is needed.
19The order needs 400 A of weld current; the selected weld cable is listed at 350 A in the guide.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a Power Wave 300C welding system: the welding process, the gun, torch or electrode holder, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the setups the public Lincoln Electric connection guide lists and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 4 Power Wave 300C welding systems (K4487-1) for TIG welding with the PTA-17F TIG torch (K1782-14), with a work cable. The weld cable is the K1796-100 (1/0 coaxial), stated as 100 ft long. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The guide lists a foot Amptrol, hand Amptrol or arc start switch with the PTA-17F TIG setup; the order has none. The order needs 320 A of weld current; the selected weld cable is listed at 300 A in the guide.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for weld current against the cable rating, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It sets the TIG switch to Foot Amptrol (K870-2).
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The order needs 320 A of weld current; the selected weld cable is listed at 300 A in the guide.
    12. 
      
  12. One finding cleared; still blocked on weld current above the weld cable rating.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the weld cable to K1842-60 (3/0 lug to lug) and the stated weld cable length as to 60 ft. It sets the stated weld cable rating as to 600 A.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
