Same-basis quotation

MIG welding equipment quoted on one scope

Welding Equipment Sourcing is an independent sourcing partner. For mig welding equipment, the desk lines up the same process, quantity, destination, currency, and delivered scope before factories are asked to price. A wire-feed photograph is not evidence that a gun, liner, or gas solenoid is included.

Keep four comparison locks in the note: exact proposed model, quantity and unit, incoterm plus US destination, and the accessory list. Voltage, wire diameter, and shielding gas are part of the model lock, not marketing adjectives. If one offer uses a 0.8 mm to 1.2 mm wire range and another stops at 1.0 mm, record that as specification deviation instead of averaging the two.

MIG delivered-cost layers to separate

A lower power-source price can look attractive when the feeder, gun, and freight are truly aligned. Comparable lifecycle scope asks whether contact tips, liners, drive rolls, and commissioning hours are inside the number. This page does not calculate a savings rate. It only keeps those layers from collapsing into one unlabeled total.

  1. Power source and feeder. Record output in amperes, duty cycle at that current, input voltage, Hz, phase, and whether the feeder is integrated. Rated power in kVA is a document field, not a number this site assigns.
  2. Gun and drive package. Note cable length in m, cooling by air or water, and liner size. A 3 m air-cooled gun and a 5 m water-cooled gun are different working envelopes.
  3. Wire, gas, and consumables. State wire diameter in mm, spool weight, and gas mix. Consumables stay off the machine price until a quotation joins them. Throughput in joints per hour is your target, not a factory claim.
  4. Packing and incoterm. Name crate limits, destination, and who arranges freight. Preventive maintenance kits can travel in the same crate or as a later line.
  5. Commissioning scope. Ask whether start-up, parameter sheets, and training hours are included. The control interface for a robot cell is a separate line if the bay uses one.

Quotation comparison questions

How should currency and budget be written?

Use one currency, such as USD, and say whether the optional target budget is per unit or for the whole order. An empty budget is acceptable. Supplier preference for a premium, mid-range, budget-friendly, or undecided posture is your buying choice. It is not a verified grade, and you do not need a live price to send the brief.

What if one quote omits gas and another includes it?

That is the lowest-price versus delivered-scope dispute in MIG form. Do not rank the offers until gas, tips, and freight sit on both sheets or are explicitly excluded on both. Ambient temperature and duty-cycle current still have to match, because a 60% rating at 200 A and 40 °C is not the same utilities requirement as a 100% rating at 150 A.

Which documents stay with the proposed model?

Ask for a current datasheet, connection drawing, and the test basis used for duty cycle. If a UL, ETL, or ISO 9001 file is offered, it must name the exact model and the supplier. This desk does not hold those certificates. A factory acceptance test can be requested. It is not already completed. Stock and lead time remain open. Noise level and ingress protection are requested only when the install environment needs them.

Where does the brief go next?

Use the TIG inquiry labels if the same shop also needs tungsten equipment, and the evidence table before approval. No upload control is on this form.

Include process, thickness in mm, wire range, gas, quantity, and destination. Price and timing are confirmed only after the proposed supplier answers. The desk will not treat a similar model name as a match.
