What is the best wire speed for MIG welding?
A recommended wire feed speed would fall in the range of 240 to 290 ipm with travel speeds between 14 and 19 ipm. A good rule of thumb is to keep the welding wire stickout at 5/8 inch or shorter for small diameter wires. It helps control amperage and with it, heat input and more.
Why is the correct electrode extension important?
The electrode extension is an important variable as it controls the degree of resistance heating of the electrode wire before it melts in the weld pool. For normal welding, the electrode extension should be 25-30mm for mild steel and rather less, say 20-25mm for stainless steels.
What should my argon regulator be set at?
Read the PSI on the left regulator gauge; it should read between 25 and 30 cubic foot-hours.
What angle is best for welding?
In the horizontal welding position, a work angle of 30 to 60 degrees works well, depending on the type and size of the joint. The goal is to prevent the filler metal from sagging or rolling over on the bottom side of the weld joint.
Can you drag when MIG welding?
Push or pull: Here the rule is simple. “If it produces slag, you drag,” says Leisner. In other words, you drag the rod or wire when welding with a stick or flux-core wire welder. Otherwise, you push the wire with metal inert gas (MIG) welding.
Should you weave when MIG welding?
When you weld each pass, treat it like a horizontal weld by weaving or swirling circles through the joint. If you’re running two passes, keep the bead narrower for the first pass.
How many Ma does an oxy IQ transmitter measure?
Certification & Safety Statements for the oxy.IQ oxygen Transmitter The oxy.IQ is a highly reliable and cost -effective two-wire, loop-powered transmitter with a linearized 4 to 20 mA output. It measures oxygen in ten ppm ranges and seven percentage ranges.
What is the maximum operating pressure for the oxy-IQ?
IMPORTANT:The maximum operating pressure for the oxy.IQ is 10 psi, and the burst pressure of the unit is 200 psi. Be sure the sample conditioning system is designed to maintain the oxy.IQ pressure below these limits, and that the oxy.IQ outlet is vented to atmosphere during operation and calibration. 3.
What are the specifications for oxy IQ installation?
Specifications oxy.IQ User’s Manual 31 Chapter 6. Specifications 6.1 Intrinsically Safe (IS) Installation Intrinsically safe installations require an MTL7706 zener barrier, one IS cable, and one non-IS cable. Power Requirements 24 to 28 VDC at 50 mA
