Anyone seen these MIG tips before?
Only found them on UK sites - no real details about them but appears you put the 'legs' on the surface and the gas can get out the 'holes'
Anyone that wleds a lot like to comment?

Yep I use them all the time on panel work. They work best with a spot timer (mine has it) if welding through the top panel, but are OK for plug welds without. You can buy them here no problem. That one is a Binzel, same as on my torch. They are cheap. Any industrial welder supply place (not toy welder shop) will have them. I had to trim the legs to get the best stickout distance for my Kemppi welder. Hint: snip the wire before doing each spot, you will get a better start. |

What's the technique for the mig spot welding using these tips? Do you need to still drill through one panel and put a puddle in the center of the hole? Or these will do it without? |

Spiffing! I have learnt something useful (at work) today.

There are MIG spot welds, and there are MIG plug welds. Spot welds- you strike an arc on the top sheet, it burns through into the 2nd sheet then stops. The timer sets the height it fills to. Yes you DO need a weld timer for this to get repeatable spots. Plug welds- you weld through the hole onto the bottom sheet until it's filled up. Timer helps here too but not essential. Note: For doing spot welds (ie no holes) the 2 sheets must be spotlessly clean where they touch, also the top should be free of paint. I have had good results with doing MIG spots even overhead, once it's set up right. IMO you want more volts and amps for doing a spot weld... but results are pretty neat.

One method for "home style" MIG spot welding I've been shown by a certain member on here (:wink:) is to drill through both panels that you intend to spot weld together. You then clamp (very tightely) a strip of metal, either aluminium or copper to the underside of the two panel you wish to spot weld together. The welder should strike an arc on the metal, but the steel weld shouldn't stick (unless you put loads of heat into it, but it still should break away with a hammer) leaving you with a nice, round and falt weld that looks a bit like a spot weld. I'm better at showing people things rather than explaining over a forum... |
