CUSTOMER VIDEO 13 OVERHEAD MIG, PULSE SPRAY MIG, AND STICK
This Video is about Short arc MIG, Pulse Spray, and Stick welding with 7018
ALL DONE IN OVERHEAD POSITION
For the first tip on overhead mig welding, I used a little primeweld MIG180 and I set the wire speed a bit lower than the recommended setting.
I find that the wire speed settings on MIG charts are often too high to work for overhead. The recommended setting for .035" wire was 236 and I lowered that to 200 inches per minute and got better results.
Have you heard of pulse spray MIG welding?
Pulse spray MIG is a modified version of spray transfer. Pulse spray mig requires a machine that has pulse capabilities along with a different gas like 90/10.
Miller , Lincoln, Esab, and others all list their pulse settings a bit differently but usually there will be a setting called "trim" or "arc length" that really makes a difference.
There are several pulse spray videos over at welderskills.com
Lets talk about Overhead Stick welding.
In my opinion a 3/32" 7018 is one of the most versatile stick welding rods.
One reason is you can usually weld with a 3/32" 7018 using 115volt power.
So I plugged my CKmt200 tig welder into a 115volt socket to see if I could weld with a 3/32" 7018.
At 90 amps, I popped a breaker before I could burn a whole rod.
but at 87 amps, I had no issues.
When you have to do some portable welding, being able to run off of 115 volt power can really save the day.
Sometimes it takes longer to unroll welding leads than it does to make the weld and with a small 40 lb inverter welder that can run off 115 volt power, being able to make a weld with 3/32"7018 can make you some money.
