1 Introduction

1.1 Welcome

Welcome to the Standard Bots RO2 Welding System Manual.

This guide covers everything you need to set up and operate a robotic MIG welding cell using the Standard Bots RO2 and the Miller Auto DeltaWeld™ 350 Basic power source. Whether you’re an integrator building a cell from scratch or an operator getting a system up and running, this manual is designed to walk you through the process from start to finish.

The RO2 and Auto DeltaWeld 350 communicate over Modbus TCP, and all I/O mapping between the two systems comes preconfigured. That means your job is to make the physical connections, set IP addresses, activate the connection, and start welding.

If you ever need help along the way, we’re here to assist.

1.2 System Overview

The complete welding system consists of the following components:

Power Source & Wire Feed

Miller Auto DeltaWeld™ 350 Basic — the welding power source, rated at 350A at 60% duty cycle. Supports MIG, Accu-Pulse, RMD, Versa-Pulse, HD MIG, and Profile Pulse processes. Communicates with the RO2 via Modbus TCP over Ethernet.
Auto DeltaWeld Basic Fixed Wire Drive — mounts to the robot or a fixed position near the cell. Feeds welding wire to the torch at speeds up to 780 ipm.
ArcConnect™ Cable (90 Degree) — connects the wire drive to the power source, carrying both power and high-speed communication signals.
Auto DeltaWeld Base and Spool Support — provides a stable mounting platform for the wire spool.
Cover, Spool 12 in. Assembly LH — protects the wire spool from contamination and damage.

Torch & Consumables

Tregaskiss RA1 Cobot MIG Gun — robotic MIG torch designed for collaborative robot applications.
Gun Mount Assembly (45 Degree) — mounts the torch to the RO2 tool flange at a 45° angle.
KUKA Insulating Disc — provides electrical insulation between the torch mount and the robot arm.
Nozzle 5/8 in. Bore, 1/8 in. Recess — standard nozzle for the RA1 torch.
Acculock Robotic Diffuser Slip — gas diffuser for the torch assembly.
0.035 Acculock Contact Tips — replaceable contact tips sized for 0.035 in. welding wire.

Wire & Drive Components

Kit, Drive Roll .035/.045 V-Groove 4 Roll — drive rolls for feeding 0.035 in. or 0.045 in. solid wire.
E70S-6 .035 x 33 lb. Spool — ER70S-6 mild steel welding wire, 0.035 in. diameter.

Work Connection

Kit, Industrial MIG 4/0 — work cable and clamp for connecting the welding circuit to the workpiece.

Robot

Standard Bots RO2 — the collaborative robot arm and control box. Refer to the RO2 User Manual for full robot documentation.
