Spot Welding in the past had primarily been done by large resistance welders but can now be
achieved with your MIG welder and this Spot Welding Kit from Eastwood. Spot welding is accom-
plished by clamping two panels together and fusing them with a number of welds sequentially-placed
rather than a continuous bead to hold the panels together. This kit is designed to be used with Tweco
Style MIG torches.
WARNINGS
• Follow all safety measures outlined in your welder's instruction manual.
• Do not touch nozzle or pliers while welding.
• Use caution when touching pliers as they may be hot and could cause burns.
• Always use a minimum Shade 10 welding helmet, welding gloves, long sleeve shirt and pants.
SPECIFICATIONS
Spot Weld Kit includes:
• Spot Weld Pliers
• Spot Weld Nozzle
• 3/16" Double-Ended Drill Bit
• Instructions
SET UP
1. Unplug MIG welder and remove gas nozzle on the end of the torch.
2. Install the supplied Spot Weld Nozzle. Once the Nozzle is installed the welder can be plugged
back in. NOTE: This Nozzle is designed to fi t the Eastwood MIG Welders but will also work on
any other Tweco Style Torch. The Spot Weld Nozzle "standoffs" do not have to be oriented in
any particular position to function properly.
3. Before using on your project it is necessary to test technique and machine settings on
scrap metal. The following suggestions are recommendations for the initial settings on the
Eastwood MIG Welders, but you may have to fi ne-tune the voltage or wire speed to achieve
perfect spot welds.

OPERATION
1. Determine a plan of action and use a scribe to mark where each spot weld should be placed
on the top panel. Clean all metal surfaces which will be in contact with a fl ap disc. Be sure to
®
remove all paint, scale, oil, etc.
2. If using a MIG135 or most other 110V welders, it is necessary to drill or punch a hole in the top
panel being spot welded. Use the included 3/16" drill bit to drill a hole through the TOP PANEL
ONLY. If using a MIG175 or most other 220V welders in most cases you will not need to drill or
punch a hole in the top panel.
3. Use the supplied Spot Weld Pliers to
clamp the top and bottom panels being
spot welded together. Put the U shape
of the pliers around the area to be spot
welded. If using the MIG135, center the
U shape around the hole drilled in the
previous step. See the image at right for
reference.
4. Place the "standoffs" of the Spot Weld
Nozzle in the 'U' of the clamp.
5. Hold the trigger to activate the arc for
2-3 seconds. Adjust the time accordingly
after trying on test panels.
6. Release and pull back the torch to reveal the spot weld. If possible make sure that the spot
weld fully penetrated before continuing on.
7. Continue on to fi nish all of the predetermined spots for the welds. It is benefi cial to move
around when welding rather than doing the spot welds all consecutively as it could overheat the
panel and causing warping.
