K-BUG 3000 & 

K-BUG 3000-BAT

A magnetic travel carriage with oscillation for welding in all positions.

The K-BUG 3000 and the K-BUG 3000-BAT are digital, compact, heavy duty fillet welders with oscillation designed for welding fillet joints. A lightweight, portable carriage utilizes powerful magnets and guide wheel clamps to track directly to the work piece. The compact lightweight design allows the machine to be taken to the workpiece to fit in confined spaces. By taking the gun out of the operator’s hand there is less fatigue for the welder. No more starting and stopping for welds longer than 16 inches. When the K-BUG 3000 / K-BUG 3000-BAT carries the torch, it provides uniform heat input and puts the right amount of weld in the right place.

The K-BUG 3000 and the K-BUG 3000-BAT feature programmable control of weave parameters that include tractor speed, weave speed and weave width. This K-BUG also has independent settings for left / right dwell. Both the K-BUG 3000 and the K-BUG 3000-BAT have the capability to perform in horizontal, vertical and flat positions. Maximum vertical lifting capacity is 50 lbs (22.7 kg). Safety cables are recommended to protect the operator and equipment. Control of all tractor and welding functions can be set or adjusted on the tractor’s panel or remotely via remote control. Remote range is up to 32 ft (10 m) away.

Choose between five weave patterns with just a push of a button.


  1. NO WEAVE– Straight line
  2. RUN– The tractor moves continuously during the weave and dwell
  3. WEAVE– The tractor and weave both stop during dwells
  4. STEP– The tractor is stationary during the weave and moves only during the dwell
  5. TRACTOR STOP ON DWELL– While the weave moves away from the tractor, the tractor is stationary. While the weave moves toward the tractor, the tractor also travels.
