Predictika · Welding power source quotes

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

An AI sales agent prepares a quote for an inverter welding power source with its wire feeder: a model, the input supply, the welding process, the current and duty cycle the job needs, the wire and the kits. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published brochure data and returns a verdict, every reason and the figures it computed.

Scope: Daihen (OTC DAIHEN) Welbee inverter power sources WB-M350, WB-M350L, WB-M500, WB-P400 and WB-P500L with the CM-742U, CMRE-742 and AF-4012 wire feeders. See everything this validator covers

This validator models quotes for the Daihen Welbee inverter series and its three wire feeders as published in the Welbee brochure (read October 9, 2026), not just the scenarios shown below.

  • Power source and input — which input phase and voltage each model is offered on (WB-M350 and WB-M350L on 1 or 3 phase at 208/230 or 460 V, WB-M500 and WB-P500L on 3 phase at 460 V, WB-P400 on 3 phase at 208/230 or 460 V), and the pulse MIG process, which is a feature of the WB-P400 and WB-P500L only.
  • Output and duty cycle — the rated output current of each model and input for MIG, pulse MIG, TIG and stick welding, the total output of the power sources quoted against the figure the quote states, and the rated duty cycle: a higher duty cycle goes to a person, because the brochure gives it only at the rated current.
  • Wire feeder, wire and kits — the feeder that fits the application (CM-742U semiautomatic, CMRE-742 automatic and robot retrofit, AF-4012 OTC DAIHEN robots), the usable wire diameters for steel, stainless and aluminum, the aluminum wire kit and the water-cooled hardware kit; a steel or stainless diameter that the brochure shows in parentheses goes to a person.

Any quote for these power sources and feeders that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published, so this validator produces no price build-up or line-item quote), other Daihen and OTC DAIHEN products, robots and positioners, torches, cables, gas, and the Tweco connection and voltage detection kits. Assumptions: pulse MIG is treated as offered on the WB-P models only, because only they show pulse ratings; the AF-4012 is treated as the feeder for OTC DAIHEN robots and the CMRE-742 for other automatic and retrofit robot use; the stick rating for the WB-M350 is taken as 300 A, the rated output current shown.

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
Input phase and voltage that differ by modelOnly with care
Each model is offered on its own combinations of phase and voltage, so a product rule per model is needed and has to be kept in step with the brochure.		The combination is checked against the model chosen, with everything else.
A rated current that depends on model, input and processOnly with workarounds
The rating changes with the model, the single or three-phase input and the process, so it takes a lookup that a typical product rule does not provide, and the job's current has to be compared with it.		The rating is looked up from model, input and process, and the current is compared with it on every call.
Pulse welding on some models onlyOnly with care
A rule can say which models have the feature, and it has to be kept in step as models are added.		The process is checked against the model chosen.
A feeder that must fit the application, wire diameters per wire material, and kits that some choices requireOnly with workarounds
Compatibility between the feeder and the application, a diameter list for each wire material and optional kits that a material or torch makes necessary are several separate rules, and a missed one lets a wrong quote through.		All of them are checked together, and each missing kit is reported by name.
A duty cycle that the brochure gives only at the rated currentOnly with workarounds
Blocking the hard limits while sending an uncertain one to a person needs an approval route that a typical product rule does not provide.		The hard limits block and the duty cycle goes to a person with the reason, in the same answer.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for an inverter welding power source with its wire feeder: a model, the input supply, the welding process, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published brochure data 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 three Daihen Welbee WB-M350L power sources on 3-phase, 460 V input for pulse MIG welding, with the CM-742U wire feeder for manual welding. The job needs 300 A at a duty cycle of 40 percent, with 1.2 mm soft aluminum wire and an air-cooled torch. The rest of the request is on screen. The quote states 1,050 A of welding output in total.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The WB-M350L is a standard (non-pulse) power source; pulse MIG is a feature of the WB-P400 and WB-P500L. The quote uses soft aluminum wire but does not include the K5870E00 Aluminum Wire Kit; the feeders are set up for hard wires as standard.
    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 pulse welding on some models only, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the power source to WB-P400 and the stated total output to 1,200 A.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The quote uses soft aluminum wire but does not include the K5870E00 Aluminum Wire Kit; the feeders are set up for hard wires as standard.
    12. 
      
  12. One finding cleared. Still blocking: aluminum wire kit missing.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the aluminum wire kit to included.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    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. Now you can try the other scenarios yourself.
    19.
