The CDDP1000 industrial spot welders provide a substantial amount of weld energy along with a fine range of power adjustment. These welders provide up to 1000 watt-seconds of energy for thicker, more conductive, and highly-resistive materials.  Weld energy can be adjusted by increments of 10ws making it extremely versatile for a variety of industrial spot welding applications.

    The best protection your investment has ever seen!


As with Sunstone Engineering’s other dual pulse spot welders, the CD1000DP industrial spot welders produce clean, strong welds. Each pulse can be adjusted to control the amount of energy released and can be turned on/off independently. Pulse one heats the weld area to eliminate surface contaminants and to seat the welding electrodes. Pulse two provides the energy to form the actual weld. Both pulses occur almost simultaneously with each weld initiation.

When combined with Sunstone’s new line of weld heads, the CDDP industrial spot welder can form strong, precise, and repeatable welds.

Introducing the Sunstone Circle Protection Plan


For your welder, it's a scary world out there! Welders get dropped, get abused, or just stop working. You have to protect your welder for any unfortunate incident. And the Sunstone Circle Protection Plan is an innovative way to safeguard your welder investment.

The Sunstone Circle is much, much more than an extended warranty. Here's what a small monthly subscription will deliver in peace of mind and exceptional customer service:

Sunstone Circle Protection Plan

Forever Warranty
For as long as your welder is covered by the Sunstone Circle your warranty never expires. You’ll never deal with lifeless warranty extensions, but rather enjoy a forever warranty. And that’s a big circle of protection!

Complimentary Loaner
If you need a loaner unit while your welder is being repaired, we’ll send one. We’re going to do all we can to keep your production levels up. If you’re in the circle, we’ll take care of you!

Free Replacement
Sometimes it makes more sense to simply replace a welder with the newest model rather than make a repair. At Sunstone’s discretion, we’ll send you the newest model to keep your shop happy and healthy!

Free Software Upgrades
When your welder is powered by the latest software improvements your shop becomes more productive and capable. You’ll have access to all software upgrades when you join the Sunstone Circle!

Complimentary Shipping
Should your Sunstone welder ever need repair, we’ll cover the shipping costs for ground service within the United States. If you need it faster, simply pay the difference. Need it shipped internationally? Give us a call!

Expedited Customer Service
At Sunstone every customer is a VIP, but when you’re part of the circle your request for customer service gets moved to the front of the line. You get extra attention! Just another perk when you subscribe today.

More Valuable Member Benefits!
You’ll receive snazzy Sunstone swag, a subscription to Micro Welding Today magazine, invitations to VIP events, Inside the Circle e-newsletter, and new product trial opportunities. Call now to join the circle!
