Using a Portable Power Center with your Leister Varimat V2

July 25, 2011

We’ve stated before that you can only use 100′ of extension cord running from your generator when running your Leister Varimat V2.  Some contractors would rather leave their generators on the ground, or wish to have a larger welding radius to work with on the roof.  In order to add an additional 100′ of cord, you need to use a portable power center, also known as a spider box.

The generators we sell come with several different receptacles.  Generally, if you’re running your Varimat directly off the generator, you’ll use the 230V receptacle (L6-30 type plug).  If you want to run off the portable power center, you’ll need to run a heavier 8 gauge drop cord from the generator to the spider box, and then you can run your 10 gauge extension cord from the spider box to your Varimat.

When using a power center between the generator and a Leister Varimat V2 or V the following is most important.  The power box has the one 220-240 outlet for the Varimat and some number of 120 outlets. When using a 12kw generator you can run the Varimat and 2 hand held Triac-S if connected properly.  The 120 outlets are arranged in side A and B, which are on each leg of the 220 circuit.  Between the 2 legs you have a 50 amp service with the Varimat requiring 20+ amps and 2 Triacs requiring 14 amps each.  There is sufficient power if only 1 Triac is on side A and the other is on side B.  If both Triacs are on side A or side B, the amperage is cumulative and 28 amps are being consumed.  This leaves only 22 amps for the Varimat.  With just a little voltage loss the Varimat could be short of it’s required amperage and will cause circuit board damage.

The moral is, remember to divide the 120 power usage between the side A and B.  Additionally NEVER use screw guns on the same generator that is powering a Leister Varimat V or V2.


Are you getting value for your fall arrest safety buckets?

July 12, 2011

With the rush to conform to the new OSHA ruling regarding the use of slide guards as a primary form of fall protection, there has been a run on safety buckets.

OSHA recently implemented a 3 month phase-in of this rule, to give contractors the time to properly implement new training and safety measures.  Now that you can no longer use slide guards as your primary source of fall protection, you should look into outfitting yourself and your crews with the proper fall protection.  Safety buckets are the primary (and cheapest) way to conform.  But don’t be drawn in just by the price tag.  There are varying levels of quality when it comes to these buckets.  Are you getting value for your dollar’s worth??

We make our buckets with a high quality 5 point harness.  Most of the “cheap” kits only contain a 3 point harness.  If you are involved in a fall on the roof, wouldn’t you feel better knowing you have those 2 extra points of connection (not to mention there is less pain in a fall when wearing a 5-point harness)?

Another feature that sets us apart is our use of a blue poly steel rope, as opposed to the polydac ropes that may be prone to fraying.  Blue poly steel ropes do not absorb water (nylon rope, when wet, will become 10-15% weaker than dry ropes) and is 10 times stronger than polypropylene.

We have been providing safety buckets to the Roofing Industry for over 20 years.  We have vendors that are known for their quality.  Remember, these buckets are for your workers or customers safety.  Don’t just buy price, buy quality.  A few dollars can mean the difference between life and the other option.
