mikesz Posted September 11, 2010 Share Posted September 11, 2010 I came across this post on a welding forum.Since i don't have a 220 outlet in my pole barn yet,I made this extension cord and it works great. http://weldingweb.com/showthread.php?t=11537 Quote Link to comment Share on other sites More sharing options...
Moltar Posted September 11, 2010 Share Posted September 11, 2010 Ha! I followed this exact writeup 2 years ago when I needed to make a 220v whip. Cost me about $60 for a 20' whip. Home Depot sells 10-3 wire by the foot (just offering an alternative to buying and cutting an extension cord). Quote Link to comment Share on other sites More sharing options...
SATAN Posted October 15, 2010 Share Posted October 15, 2010 So wait... There is no ground strap? I made my own extension cord too for my TIG. Only, I used the actual 220v cable that they sell. It has 4 wires, Red, black, White and a bare copper. Red and Black are power, White is Common and copper ground strap. I think it cost me like $50 to make a 12' cord with a receiver box. I have it wired directly into my breaker box. This gets my TIG anywhere I need it in my garage. So is it ok to do it without running the bare copper wire?

BLOZ UP Posted October 17, 2010 Share Posted October 17, 2010 Yes. If you connected the hot, neutral and ground correctly, they are all you need. I wouldn't go welding barefoot in puddles though. >150mA is deadly. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 18, 2010 Share Posted October 18, 2010 There is always the possibility of a local ground connection to earth via static line as well. Very common in the field. Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted October 18, 2010 Share Posted October 18, 2010 (edited) I would use the ground strap and ground the case of your TIG at least. Miller recommends your table and nearby metal structures as well. If you're using HF, especially continuously with aluminum, theres a chance you are giving off a lot of radio interference. I've heard stories of people shutting off they're neighborhoods internet access when TIG welding... Miller has a great guide on their website about grounding their units. For a MIG you'd probably be fine with the 3 wire. Or ground with a stake near your work like Tony says.

Tony D Posted October 20, 2010 Share Posted October 20, 2010 A hammer drill, 18" long bit, and a driver is all it takes to access a proper ground rod in the garage floor. It's easier than you would think. And if you put it in the right place, it comes in handy for all sorts of grounded crap. I actually have a properly grounded anti-static workbench (thanks JeffP) for about 20 minutes of work. Driving the rod is the biggest pain as I have to drive into Decomposed Granite at about 4 feet... the first 4 are lit butter. That last two feet takes a while!
