Predictika · Engine-driven welder orders

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

An AI sales agent prepares an order for Ranger engine-driven welder generators: a model and fuel, the number of welders, the welding amps and auxiliary power, the wire feeder and spool gun, the weld cable, the altitude, a discount and the total it states in US dollars. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the order rules and returns a verdict and every reason.

Scope: Lincoln Electric Ranger welder orders: model and fuel, welding amps, auxiliary power, LN-25 PRO feeder and spool gun, cable size, quantity, altitude, discount and the stated total. See everything this validator covers

This validator models Ranger welder orders of this kind, not just the scenarios shown below.

  • Model, fuel and power — the LPG and gasoline variants, the welding amps each model is rated for, and the auxiliary power the generator can supply, alone or while welding.
  • Accessories and cable — the LN-25 PRO wire feeder that is not offered with the Ranger 225, the spool gun that needs the feeder, and a weld cable size that suits the amps and the length.
  • Quantity, price and review — the order size, discounts and the volume they need, large orders, high altitude, and the stated total compared with the computed one.

Any Ranger welder order that touches these rules is in scope — not only the scenarios pictured here. Model names, the gasoline and LPG variants, the amps by model name and the LN-25 PRO feeder and Magnum PRO 250LX spool gun follow public reseller and Lincoln Electric listings; the generator ratings used, accessory compatibility, cable rules, thresholds and every dollar price are modeled and not published by Lincoln Electric, so the prices on this page are illustrative. Not covered: other products, freight, taxes and service.

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
Ratings that differ by modelOnly with care
Each Ranger model is rated for different welding amps and generator watts, so every model needs its own rule against the amps and power asked for.		The model, the amps and the power are fields of one request and are checked together.
Accessories that depend on the model and each otherOnly with care
The feeder is not offered with the 225 and the spool gun needs the feeder, so each accessory needs rules on the model and on the other accessory.		The model and every accessory are checked together on every call.
A cable size that depends on amps and lengthOnly with workarounds
The cable needed grows with the amps and the length, so a rule must work out the size needed before it compares it with the cable chosen.		The amps, length and cable are in one request, and the size needed is computed on every call.
A total built from many partsOnly with workarounds
The total depends on the model, accessories, cable, quantity and discount, so it must be computed before it can be compared with the total stated.		The total is computed on every call and compared with the total stated in the order.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is saved or 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
Click to expand
    
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 order is for 0 welders; a single order takes 1 to 50.
2The order is for 51 welders; a single order takes 1 to 50.
3An order for 11 welders is above 10, so a person should confirm stock and price.
4The requested fuel does not match the chosen Ranger model; the LPG variants are the Ranger 260MP LPG and Ranger 305 LPG, the others run on gasoline.
5226 welding amps are requested; the chosen Ranger model is rated to 225 amps.
6261 welding amps are requested; the chosen Ranger model is rated to 260 amps.
78,001 watts of auxiliary power are requested; the modeled generator rating is 8,000 watts.
8Welding at the same time as 4,001 watts of auxiliary power is above the modeled limit of half the 8,000 watt generator rating.
9The LN-25 PRO wire feeder is requested with the Ranger 225; the modeled rule keeps the 225 as a stick and TIG machine.
10The Magnum PRO 250LX spool gun is requested without an LN-25 PRO wire feeder.
11The chosen weld cable size is too small for 250 amps over 101 feet.
12The chosen weld cable size is too small for 301 amps over 101 feet.
13Operation at 6,001 feet is above 6,000 feet, where engine power and generator output are reduced; a person should confirm the model.
14A discount of 8 percent on 4 welders is above 3 percent, so a person should approve it.
15A discount of 9 percent is above the modeled 8 percent limit.
16A discount of 5 percent is requested on 2 welders; the modeled rule needs at least 3.
17The quote states a total of 100 USD; 12,700 USD before a 0 percent discount gives a different figure (stated totals are rounded to the dollar).
18The quote states a total of 12,701 USD; 12,700 USD before a 0 percent discount gives a different figure (stated totals are rounded to the dollar).
19A discount of 5 percent on 12 welders is above 3 percent, so a person should approve it.
20An order for 12 welders is above 10, so a person should confirm stock and price.
21Operation at 7,000 feet is above 6,000 feet, where engine power and generator output are reduced; a person should confirm the model.

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 Ranger engine-driven welder generators: a model and fuel, the number of welders, the welding amps and auxiliary power, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the order rules and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 2 Ranger 225 welders on LPG fuel at 260 welding amps with 50 feet of 1/0 cable, with the LN-25 PRO wire feeder. The discount is 5 percent. The rest of the request is on screen. The order states a total of 16,625 US dollars.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The requested fuel does not match the chosen Ranger model; the LPG variants are the Ranger 260MP LPG and Ranger 305 LPG, the others run on gasoline. 260 welding amps are requested; the chosen Ranger model is rated to 225 amps. The LN-25 PRO wire feeder is requested with the Ranger 225; the modeled rule keeps the 225 as a stick and TIG machine. The other two are on screen.
    6. 
      
  6. The validator returned five 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 ratings that differ by model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to Ranger 260MP, the fuel to gasoline, the weld cable to 2/0 (50 ft), the discount to 0 percent and the stated total to 18,600.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
