No Need for PUSH/PULL with Pro Spot

Save your money!

When you're out looking for a MIG welder, especially in this Aluminum Rush, you'll come across the words "Push Pull" a lot. Let's explain about what it is, and when or why you would need it.
There are many welders out there, some that feature a Push Pull torch, and some that don't... why?

When welding soft metals, like aluminum, the welding wire has a tendency to bend easily. When the welding wire bends while being fed through the drive rollers, the wire gets tangled, appearing like a birdnest. When this occurs, the wire needs to be cut, removed from the torch, and re-fed through the drive rollers & torch. If you don't know about birdnesting... you're lucky! It causes downtime, frustration and loss of welding wire.

Push/pull systems require two separate wire feed motors, one at the torch end and one in the cabinet, which both need to run at the exact same speed for the system to operate correctly. If one roller glitches and the two rollers get off track, the torch will jam and cause birdnesting. A common use for push/pull torches is in the industrial industry for long-distance welding, where the wire has to travel through extra long cables. 


There are MIG welders that don't need a complicated or expensive push/pull system.
The Pro Spot SP MIG Series Welders (with Pulse technology) start the welding process before the wire comes in contact with the base metal, preventing the sudden shock to the wire, which causes the "birdnesting" at the roller. The Pro Spot aluminum torches also incorporate a graphite liner in the torch, which leads the wire though for smooth wire feed.




Like we said before, if you don't know about birdnesting... you're lucky! It causes downtime, frustration and loss of welding wire. 

Your options to prevent it in aluminum welding are: going with a system like the Pro Spot SP MIG welders with the early arc and graphite liner or with other systems that require purchasing a Push/Pull torch.
