Welding Robots
9 six-axis welding robots for MIG/MAG, TIG and spot work, 6 to 210 kg payload and 1440 to 3160 mm reach. In arc welding the payload carries only the torch and its cable package, so reach and repeatability decide the choice, not lifting capacity; the heavy models exist for spot-welding guns and large weldments.
Not sure which model fits?
Send the part weight, the reach you need and the cycle. We will name the model — and say plainly if a robot is not the right answer for it.
Arc welding robots for MIG/MAG, TIG and spot welding. 9 models from 6 to 210 kg payload with reach from 1440 to 3160 mm, including PRO versions of the RH14-10-W and RH20-06-W — the same robots at a lower price, with a simpler control cabinet.
Typical work: structural steel and frames, pressure vessels and pipe spools, agricultural and construction machinery, furniture and metal fabrication. Six-axis kinematics with a hollow wrist keeps the torch cable inside the arm, which matters on long seams and rotating parts.
Payload here is not the part — it is the torch, wire feeder, cable package and any sensor. Weigh the torch package you will use and add any seam-tracking or laser sensor; the lightest welding models carry 6 kg. For parts that must be turned during welding, pair the robot with a positioner from the Welding Positioners section.

Frequently Asked Questions
Reach is measured to the furthest seam the torch must get to at full extension, not to the edge of the table. Our welding range covers 6 to 210 kg payload and 1440 to 3160 mm reach, so send us the part weight, the largest dimension and the seam layout and we will name the model that fits.
It does the same work as the rest of the series — there is no restriction on application, so the choice is a matter of budget and of which cabinet you want.
It also lets you use a smaller robot: the arm no longer has to reach around the part at awkward angles. For a flat plate or a single accessible seam, you do not need one.
Beyond the robot, the process is set by the power source and torch you pair it with, and by the payload you must allow for at the wrist.
Technical support is online: our engineers consult on setup, programming questions and fault-finding by video call. Spare parts are shipped directly from the factory.
CRP production is certified to ISO 9001, and the factory reports its products are certified to an MTBF above 100,000 hours.
