LIMITED WARRANTY
GENERAL TERMS AND CONDITIONS FOR THE SALE OF GOODS
1. Applicability.
(a) These terms and conditions of sale (these “Terms”) are the only terms which govern the sale of the goods (“Goods”) by Amada Weld Tech Inc. (“Seller”) to the
buyer identified in the Sales Quotation and/or Acknowledgment (as each defined below) to which these Terms are attached or incorporated by reference
(“Buyer”). Notwithstanding anything herein to the contrary, if a written contract signed by authorized representatives of both parties is in existence covering the
sale of the Goods covered hereby, the terms and conditions of said contract shall prevail to the extent they are inconsistent with these Terms.
(b) The accompanying quotation of sale (the “Sales Quotation”) provided to Buyer, and/or sales order acknowledgement (“Acknowledgement”) and these Terms
(collectively, this “Agreement”) comprise the entire agreement between the parties, and supersede all prior or contemporaneous understandings, agreements,
negotiations, representations and warranties, and communications, both written and oral. For clarification, after the Acknowledgement is received by Buyer, the
order for Goods is binding and cannot be cancelled by Buyer for any reason and the full purchase price amount set forth in the Acknowledgement shall be due
and payable by Buyer to Seller pursuant to the payment schedule set forth in the Acknowledgement unless otherwise agreed to in writing by Seller. All terms and
conditions contained in any prior or contemporaneous oral or written communication which are differentfrom,or in addition to, the terms and conditions in this
Agreement are hereby rejected and shall not be binding on Seller, whether or not they would materially alter this Agreement. These Terms prevail over any of
Buyer’s terms and conditions of purchase regardless whether or when Buyer has submitted its purchase order or such terms. Fulfillment of Buyer’s order does
not constitute acceptance of any of Buyer’s terms and conditions and does not serve to modify or amend these Terms. Notwithstanding anything herein to the
contrary, all orders for Goods must be for a minimum purchase price of $100 or such orders will be rejected by Seller.
2. Delivery.
(a) The Goods will be delivered within a reasonable time after Seller provides Buyer the Acknowledgment, subject to availability of finished Goods. Seller will
endeavor to meet delivery schedules requested by Buyer, but in no event shall Seller incur any liability, consequential or otherwise, for any delays or failure to
deliver as a result of ceasing to manufacture any product or any Force Majeure Event. Delivery schedules set forth in the Acknowledgment are Seller’s good faith
estimate on the basis of current schedules. In no event shall Seller be liable for special or consequential damages resulting from failure to meet requested
delivery schedules.
(b) Unless otherwise agreed in writing by the parties in the Acknowledgement, Seller shall deliver the Goods to the Seller’s plant in Monrovia, CA, USA (the
“Shipping Point”) using Seller’s standard methods for packaging and shipping such Goods. Buyer shall take delivery of the Goods within three (3) days of Seller’s
written notice that the Goods have been delivered to the Shipping Point. Buyer shall be responsible for all loading costs (including freight and insurance costs)
and provide equipment and labor reasonably suited for receipt of the Goods at the Shipping Point. Seller shall not be liable for any delays, loss or damage in
transit.
(c) Seller may, in its sole discretion, without liability or penalty, make partial shipments of Goods to Buyer, if applicable. Each shipment will constitute a separate
sale, and Buyer shall pay for the units shipped whether such shipment is in whole or partial fulfillment of Buyer’s purchase order.
(d) If for any reason Buyer fails to accept delivery of any of the Goods on the date fixed pursuant to Seller’s notice that the Goods have been delivered at the
Shipping Point, or if Seller is unable to deliver the Goods at the Shipping Point on such date because Buyer has not provided appropriate instructions, documents,
licenses or authorizations: (i) risk of loss to the Goods shall pass to Buyer; (ii) the Goods shall be deemed to have been delivered; and (iii) Seller, at its option, may
store the Goods until Buyer picks them up, whereupon Buyer shall be liable for all related costs and expenses (including, without limitation, storage and
insurance).
3. Non-delivery.
(a) The quantity of any installment of Goods as recorded by Seller on dispatch from Seller’s place of business is conclusive evidence of the quantity received by
Buyer on delivery unless Buyer can provide conclusive evidence proving the contrary.
(b) Seller shall not be liable for any non-delivery of Goods (even if caused by Seller’s negligence) unless Buyer gives written notice to Seller of the non-delivery
within three (3) days of the date when the Goods would in the ordinary course of events have been received.
(c) Any liability of Seller for non-delivery of the Goods shall be limited to (in Seller’s sole discretion) replacing the Goods within a reasonable time or adjusting the
invoice respecting such Goods to reflect the actual quantity delivered.
4. Shipping Terms. Unless indicated otherwise in the Acknowledgment, Delivery shall be made EXW (Incoterms 2010), Shipping Point, including without
limitation, freight and insurance costs. If no delivery terms are specified on the Acknowledgement, the method of shipping will be in the sole discretion of Seller.
Unless directed in writing otherwise by Buyer, full invoice value will be declared for all shipments.
5. Title and Risk of Loss. Title and risk of loss passes to Buyer upon delivery of the Goods at the Shipping Point. As collateral security for the payment of the
purchase price of the Goods, Buyer hereby grants to Seller a lien on and security interest in and to all of the right, title and interest of Buyer in, to and under the
Goods, wherever located, and whether now existing or hereafter arising or acquired from time to time, and in all accessions thereto and replacements or
modifications thereof, as well as all proceeds (including insurance proceeds) of the foregoing. The security interest granted under this provision constitutes a
purchase money security interest under the California Commercial Code.
6. Amendment and Modification. These Terms may only be amended or modified in a writing which specifically states that it amends these Terms and is
signed by an authorized representative of each party.

7. Inspection and Rejection of Nonconforming Goods.
(a) Buyer shall inspect the Goods within two (2) days of receipt (“Inspection Period”). Buyer will be deemed to have accepted the Goods unless it notifies Seller in
writing of any Nonconforming Goods during the Inspection Period and furnishes such written evidence or other documentation as required by Seller.
“Nonconforming Goods” means only the following: (i) product shipped is different than identified in Buyer’s Acknowledgement; or (ii) product’s label or
packaging incorrectly identifies its contents. Notwithstanding the foregoing, for shipped Goods that require field installation, the “re-verification” terms in the
Acknowledgement shall apply and for custom installations, the inspection and verification shall take place at Buyer’s site immediately after the installation is
completed.
(b) Seller will only accept Nonconforming Goods that are returned under Seller’s Return Material Authorization procedures then in effect (“RMA”). Buyer shall
obtain a RMA number from Seller prior to returning any Nonconforming Goods and return the Nonconforming Goods prepaid and insured to Seller at 1820 South
Myrtle Avenue, Monrovia, CA 91016 or to such other location as designated in writing by Seller for the examination to take place there. If Seller reasonably
verifies Buyer’s claim that the Goods are Nonconforming Goods and that the nonconformance did not developed by use from Buyer, Seller shall, in its sole
discretion, (i) replace such Nonconforming Goods with conforming Goods, or (ii) credit or refund the Price for such Nonconforming Goods pursuant to the terms
set forth herein. Notwithstanding the foregoing, the only remedy for Nonconforming Goods that are custom systems is repair (not refund or replacement). No
returns for Nonconforming Goods are allowed after thirty (30) days from the original shipping date.
(c) Buyer acknowledges and agrees that the remedies set forth in Section 7(a) are Buyer’s exclusive remedies for the delivery of Nonconforming Goods. Except as
provided under Section 7(a) and Section 14, all sales of Goods to Buyer are made on a one-way basis and Buyer has no right to return Goods purchased under this
Agreement to Seller.
8. Price.
(a) Buyer shall purchase the Goods from Seller at the prices (the “Prices”) set forth in Seller’s published catalogue literature in force as of the date of the Sales
Quotation. However, the Prices shown in such catalogue literature or any other publication are subject to change without notice. Unless specifically stated to the
contrary in the Sales Quotation, quoted Prices and discounts are firm for thirty (30) days from the date of the Sales Quotation. Unless otherwise stated, prices are
quoted EXW (Incoterms 2010), Shipping Point. Unless otherwise stated in the Acknowledgement, if the Prices should be increased by Seller before delivery of the
Goods to a carrier for shipment to Buyer, then these Terms shall be construed as if the increased prices were originally inserted herein, and Buyer shall be billed
by Seller on the basis of such increased prices.
(b) All Prices are exclusive of all sales, use and excise taxes, and any other similar taxes, duties and charges of any kind imposed by any governmental authority on
any amounts payable by Buyer. Buyer shall be responsible for all such charges, costs and taxes (present or future); provided, that, Buyer shall not be responsible
for any taxes imposed on, or with respect to, Seller’s income, revenues, gross receipts, personnel or real or personal property or other assets.
9. Payment Terms.
(a) Unless otherwise provided in the Acknowledgement, if Buyer has approved credit with Seller, Buyer shall pay all invoiced amounts due to Seller within thirty
(30) days from the date of Seller’s invoice. If Seller does not have Buyer’s financial information and has not provided pre-approved credit terms for Buyer, the
payment must be made in cash with order or C.O.D. in US dollars. If Buyer has approved credit terms, the payment may be made by cash with order, wire
transfer of immediately available funds, or check in US dollars. Certain products require a down payment. Any payment terms other than set forth above will be
identified in the Acknowledgement. Notwithstanding anything herein to the contrary, all prepaid deposits and down payments are non-refundable. If a deposit
is not received when due, Seller reserves the right to postpone manufacturing of Goods until payment is received. Seller will not be responsible for shipment
delays due to deposit payment delays.
(b) In Seller’s sole discretion, Seller may access Buyer interest on all late payments at the lesser of the rate of 1.5% per month or the highest rate permissible
under applicable law, calculated daily and compounded monthly. Buyer shall reimburse Seller for all costs incurred in collecting any late payments, including,
without limitation, attorneys’ fees. In addition to all other remedies available under these Terms or at law (which Seller does not waive by the exercise of any
rights hereunder), Seller shall be entitled to suspend the delivery of any Goods if Buyer fails to pay any amounts when due hereunder and such failure continues
for ten (10) days following written notice thereof.
(c) Buyer shall not withhold payment of any amounts due and payable by reason of any set-off of any claim or dispute with Seller, whether relating to Seller’s

third party software that may accompany the Goods or otherwise and such software is explicitly included in the definition of Third Party Products below.

both parties. If the party-selected arbitrators are unable to agree upon the third arbitrator, if either party fails to select an arbitrator, or in the case that only one
arbitrator is required and the parties are unable to agree, then the International Court of Arbitration shall choose the arbitrator. The language to be used in the
arbitral proceeding shall be English. The arbitrator(s) shall have no authority to issue an award that is contrary to the express terms of this Agreement or the laws
of the State of California or applicable US Federal Law, and the award may be vacated or corrected on appeal to a court of competent jurisdiction for any such
error. The arbitrator(s) shall be specifically empowered to allocate between the parties the costs of arbitration, as well as reasonable attorneys’ fees and costs, in
such equitable manner as the arbitrator(s) may determine. The arbitrator(s) shall have the authority to determine issues of arbitrability and to award
compensatory damages, but they shall not have authority to award punitive or exemplary damages. Judgment upon the award so rendered may be entered in
any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be. In
no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding based upon such claim, dispute or other
matter in question would be barred by the applicable statute of limitations. Notwithstanding the foregoing, either party shall have the right, without waiving any
right or remedy available to such party under this Agreement or otherwise, to seek and obtain from any court of competent jurisdiction any interim or provisional
relief that is necessary or desirable to protect the rights or property of such party, pending the selection of the arbitrator(s) hereunder or pending the
arbitrator(s)’ determination of any dispute, controversy or claim hereunder.
25. Notices. All notices, request, consents, claims, demands, waivers and other communications hereunder (each, a “Notice”) shall be in writing and addressed to
the parties at the addresses set forth on the face of the Acknowledgement or to such other address that may be designated by the receiving party in writing. All
Notices shall be delivered by personal delivery, nationally recognized overnight courier (with all fees pre-paid), facsimile (with confirmation of transmission) or
certified or registered mail (in each case, return receipt requested, postage prepaid). Except as otherwise provided in this Agreement, a Notice is effective only
(a) upon receipt of the receiving party, upon confirmation of delivery by nationally recognized overnight courier or upon forty-eight (48) hours after being sent by
certified or registered mail (as applicable), and (b) if the party giving the Notice has complied with the requirements of this Section 25.
26. Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction.
27. Survival. Provisions of these Terms which by their nature should apply beyond their terms will remain in force after any termination or expiration of this
Order including, but not limited to, the following provisions: Compliance with Laws, Confidentiality, Governing Law, Dispute Resolution, Survival, and the

SERIAL DATA COMMUNICATIONS
990-661 1-1
CHAPTER 1
Description
Serial Data Communications allows you to connect a single Control, or multiple Controls, to a printer or
a computer in order to:
•Retrieve, store, import, and export weld history data, display weld history data in different
graphic formats for detailed analysis.
•Remotely program weld schedules on the Control(s).
•Remotely program menu items on the Control(s).
There are two types of Serial Data Communications; RS-485 and RS-232.
RS-485 connection allows up to 20 Controls to be connected to a computer. This is used for weld
history retrieval, storage and remote weld schedule programming.
The only difference between RS-232 operation and RS-485 operation is that RS-485 can be "Daisy
Chained" for multiple controls, and RS-232 cannot.

Communications Syntax
Data and Display Formats
Most of the data fields are the same for all Power
Supplies. However, Field 1, Field 2, Field 3
, and
Field 4 for the DC25 and UB25 contain
different
data than the HF 25. An HF25D produces 7
extra
fields of data not
produced by the DC25 or UB25.
These differences are described below.
DC25/UB25
Field 1 =
Waveform stability result (% average
deviation).
Field 2 =
Waveform capacity result (% of
deviation).
Field 3 = Waveform stability result (%
average
deviation).
Field 4 =
Waveform capacity result (% of
deviation).
HF25
Field 1 = % of capacity control to reach Pulse 1.
Field 2 = Always zero.
Field 3 = % of capacity control to reach Pulse 2.
Field 4 = Always zero.
ADDITIONAL HF25D Fields
Field A
= Displacement measurement units
(inches/1000) or
(mm) depending on the
display units selected.
Field B = Displacement initial thickness value.
Field C = Displacement final thickness value.
Field D = Displacement value (initial minus
final).
Field E = Time reached in msec.
Field F = SEA limit reached.
Field G = Limit time in msec.

Communication Set-up
The following menu screens tell you how to set the Power Supplies communication options. You will
need to select between “Host” and “Client” communications role (see below for details) and data options
such as baud rate, RS-232 or RS-485 protocol, and the ID number for the weld control.
Rear-mounted RS-232 and RS-485 connectors allow for remote programming, weld schedule selection,
and data logging for SPC purposes. Data output provides the necessary process documentation for
critical applications and permits data logging for SPC purposes.
Appendix E, Communications in this manual lists all of the commands that the Power Supply will
respond to, and instructions on how to format commands sent to the Power Supply so it will respond
properly.
The Power Supply contains internal software that gives you a great deal of flexibility in the setup and
use of your welding system. The Power Supply software displays various menu screens on the LCD,
each containing prompts telling you which of the Power Supplies front panel controls to use in order to
customize operating parameters, set the Power Supply for use in an automated welding system, and
program communication settings for use with data-gathering devices such as a host computer.

•In the HOST role, the Power Supply will:
−Send weld data to the host computer after each weld operation.
−Send text data to a serial printer, providing a printout of the average voltage and
current values for each weld, generating a "paper history" of welds performed.
•In the CLIENT role, the Power Supply will send weld data only when requested by the host
computer. You must use this role for RS-485 installations with mulitple Power Supplies
on one communications channel.
